Lowri Izzard: Biography, Acting Career, Writing, and Life in Welsh Theatre
Lowri Izzard is a Welsh actress, voice artist, and writer with a varied screen and stage career. She is best known for playing Lowri Izzard? No—her best-known role is PC Mari James in the acclaimed bilingual crime drama Hidden (Craith). She has also appeared in film, radio, theatre, and television, building a career across several forms of performance.
Lowri Izzard has gained wider attention through projects such as Brian and Charles and Y Sŵn. Her work also includes Casualty, Doctors, and other screen productions. Alongside acting, she has developed a comedy writing partnership with her identical twin sister, Mari Izzard, giving her career another creative direction.
This biography looks at her training, acting work, writing projects, stage career, and voice work. It also explores her connection with Mari and the projects they have created together. Personal details that are not clearly confirmed by reliable sources are not included.
Lowri Izzard and Her Welsh Background
Lowri Izzard is a Welsh performer whose career has strong links to Wales. Public professional profiles describe her as a Welsh actress and comedy writer. She and her identical twin sister, Mari Izzard, come from Bridgend in South Wales and have described their background as working class.
Her Welsh background has also connected with the type of work she has taken. She has worked on Welsh television and radio projects while also appearing in wider British productions. This has allowed her to move between Welsh-language and English-language work.
The performer is fluent in both Welsh and English. Her voice work also includes Welsh and received pronunciation accents. Professional voice profiles note that she can work with several other accents as well.
That language range has been useful across her career. It supports work in drama, comedy, voice recording, and radio. It also fits naturally with her work in bilingual Welsh productions.
Her career therefore has a clear Welsh foundation. At the same time, her credits show that she has worked beyond one regional market. Her professional experience reaches television, cinema, theatre, radio, and voice work.
How Lowri Izzard Began Her Acting Career
The public record does not provide a detailed account of Lowri Izzard’s childhood. There is limited reliable information about her parents, early home life, or first decision to become an actor. What is clear is that she later pursued formal training and entered professional performance.
Her early career developed through theatre and screen work. She appeared in productions that allowed her to gain experience with different directors, writers, and performers. This helped establish a varied professional base.
One important early stage credit was Lord of the Flies. Lowri and her twin sister Mari appeared together in the production at Theatr Clwyd and the Sherman Theatre in 2018. They played Sam and Eric in a female-led version of the famous story.
The production offered both sisters an important theatre opportunity. It also showed how closely their creative paths could develop. Their later writing partnership would grow from that shared professional relationship.
Lowri’s early work was not limited to one kind of performance. She moved between theatre and screen roles while continuing to develop her skills. That variety became an important feature of her career.
Lowri Izzard’s Training at RADA
Lowri Izzard trained at the Royal Academy of Dramatic Art, widely known as RADA. The academy’s official profile confirms that she completed its BA in Acting degree. She graduated in 2016.
RADA training gave her a strong base for professional performance. Actor training can cover voice, movement, character work, text, and stage practice. These skills can help performers move between theatre, television, film, and audio work.
Her later career reflects that broad training. She has performed on stage and screen. She has also worked as a voice artist and comedy writer.
Lowri also developed specialist performance skills during her training. Her professional profile describes her as an award-winning stage combat performer. At RADA, she received the Henry Marshall Prize Fight Award.
Stage combat involves controlled performance techniques used for fight scenes. Actors learn how to make movement look convincing while maintaining safety. This training can add another useful skill to a performer’s stage work.
Her time at RADA was therefore an important part of her professional development. It gave her formal acting education and helped prepare her for a varied career. Her later credits show how widely she has used those skills.
Lowri Izzard’s Theatre Career
Theatre has remained an important part of Lowri Izzard’s professional work. Her stage credits include productions connected with Theatr Clwyd, the Sherman Theatre, and Wilton’s Music Hall. These venues have provided opportunities for her to perform in different styles of theatre.
Her work with Theatr Clwyd is especially relevant to her Welsh career. The theatre is one of Wales’ major producing theatres. It has a long history of developing and presenting professional stage work.
In 2018, Lowri appeared in Lord of the Flies with Mari. The production was staged at Theatr Clwyd before moving to the Sherman Theatre. Their roles were part of a modern, female-led version of William Golding’s story.
Working on stage can demand a different approach from television. Theatre performers must sustain characters through complete live performances. They also need strong voice and physical control.
Lowri’s stage combat award adds another dimension to this work. Her training has supported the physical side of performance as well as acting itself. This makes theatre an important part of her wider professional identity.
Her stage career also connects with her later writing work. Theatre gave her experience with live audiences and character-led stories. Those skills became useful when she and Mari began creating comedy together.
Lowri Izzard as a Voice Artist
Lowri Izzard has also developed a career as a professional voice artist. Her work includes radio drama, commercial voiceover, and musical recording. Her professional profile describes her voice as warm and engaging.
Voice acting requires a different kind of control from screen performance. The audience may only hear the performer rather than see them. Voice, timing, tone, and clear speech must therefore carry the meaning.
Lowri works in both Welsh and English. She can perform in Welsh and received pronunciation accents. Her profile also lists experience with several other accents, including American Standard, Cockney, Edinburgh, London, Lancashire, and French.
Her voice work adds another layer to her career. It means she can perform without relying on a visual character. Audio projects also allow actors to explore storytelling through sound alone.
Her professional interests extend into animation and gaming as well. Her voice profile notes a strong interest in immersive storytelling, especially role-playing games. She also has a particular interest in animation where music plays an important part.
These interests fit her wider creative career. She has worked in front of cameras, on stage, behind a microphone, and as a writer. Each area uses different skills while still depending on storytelling.
Lowri Izzard in Hidden (Craith)
One of Lowri Izzard’s best-known television roles is PC Mari James in Hidden, also known as Craith. The series is a bilingual BBC and S4C crime drama. Her role as the police character became a key part of her screen profile.
Hidden is a crime drama set in Wales. The series uses both Welsh and English, reflecting the setting and culture of the story. This made the production a strong match for a performer who works fluently in both languages.
Playing a police officer also placed Lowri in a serious dramatic setting. The role required her to work within a crime story rather than a straightforward comedy. It added another type of performance to her growing television record.
Her involvement in both series of the drama is noted by her professional voice agency. The role is specifically described as one of the performances for which she is best known.
The production also helped connect her with Welsh television audiences. It showed her ability to work naturally within a bilingual cast and setting. That experience became an important part of her screen career.
The role of PC Mari James remains central when discussing her television work. It helped establish her as a recognizable performer in Welsh drama. It also sits alongside her later roles in film and television comedy.
Lowri Izzard and Brian and Charles
Lowri Izzard also appeared in the feature film Brian and Charles. She played Katrina in the film, which became a notable independent comedy project. The film was connected with Film4 and the BFI and gained attention at the Sundance Film Festival.
Her involvement in Brian and Charles was important for another reason. She worked on the film alongside her identical twin sister, Mari. Their experience on the production helped lead to their later work as a writing team.
The sisters discovered that they enjoyed working together creatively. That experience became the beginning of their first official writing collaboration. Their partnership later developed through comedy writing projects.
The film also brought professional recognition for Lowri. She was longlisted for the BAFTA Breakthrough UK award in 2022 for her work connected with the film. Her professional profile records this achievement.
Brian and Charles therefore had more than one effect on her career. It gave her a notable film credit and created a stronger creative link with Mari. It also helped open the door to further writing opportunities.
For Lowri, the project shows how acting and writing can connect. A performance job became the setting for a new creative partnership. That partnership would later produce original comedy material.
Lowri Izzard and Y Sŵn
Another important film credit is Y Sŵn, in which Lowri Izzard played Manon. The feature is connected to Welsh culture and history. Her role added another Welsh-language project to her growing film record.
The film received a BAFTA Cymru nomination. That recognition placed the project within an important part of Welsh screen culture. Lowri’s involvement also strengthened the Welsh side of her professional profile.
Her work in Y Sŵn followed other projects that showed her ability to perform in different settings. She had already worked in television drama and comedy. Film gave her another space in which to develop her screen career.
The role of Manon is also notable because it sits alongside her work in Brian and Charles. These two films demonstrate the range of projects within her film credits. One is an English-language comedy with an unusual premise, while the other is closely linked to Welsh culture.
Her film career remains one part of a much wider body of work. She has not focused only on cinema. Television, theatre, radio, voice acting, and writing all form part of her professional story.
At this stage, the strongest picture of her career comes from that variety. Her training prepared her for performance. Her later projects have allowed her to use those skills across many different forms.
Lowri Izzard’s Comedy Writing Partnership
Acting has remained an important part of Lowri Izzard’s career, but writing has gradually become another major area of her creative work. A significant part of that development has come through her collaboration with her identical twin sister, Mari Izzard. The sisters work together as a writing team and have explored comedy through projects created for both stage and radio.
Their partnership developed naturally after years of working in the performing arts. One important moment came while they were involved with the film Brian and Charles. The experience helped them realize how much they enjoyed creating and working together professionally. It eventually encouraged them to develop original material as a team.
Their approach is especially connected with character-based comedy. Instead of relying only on quick jokes, their writing tends to focus on distinctive personalities and unusual situations. They have also spoken about their interest in unconventional protagonists, giving their work a recognizable creative direction.
Working as twins can also give the partnership an unusual rhythm. They share similar cultural references and professional experiences, while each can still contribute an individual perspective. Their development as writers has since brought them opportunities with major organizations in British television, radio, and theatre.
Lowri Izzard and Spoffin
A major step in Lowri Izzard’s development as a comedy writer came through Sky Comedy Rep. She and Mari were selected for the program, which was created to support emerging comedy writers and performers while allowing them to develop new material in a professional theatre environment.
Their original project was titled Spoffin. It became their first official writing collaboration and was performed as part of the Sky Comedy Rep festival at Birmingham Rep.
For Lowri, the project represented more than another performance credit. It demonstrated that her career could expand beyond acting into the creation of original comedy. Writing gives performers a different kind of control over storytelling because they can develop the characters, dialogue, setting, and comic situations from the beginning.
Spoffin also led to further professional interest. Following the stage presentation, Mari and Lowri were commissioned by Sky Studios to continue developing scripts. Their project moved into further development, showing that the original concept had potential beyond its first theatrical presentation.
The sisters have also discussed developing Spoffin for the screen. Although development does not guarantee that a project will eventually become a television series, receiving further support is an important achievement for emerging writers. It placed the pair within a professional comedy-development environment and gave them experience building an idea for another medium.
Lowri Izzard and The Garden Centre
Radio has provided another outlet for Lowri Izzard’s writing. Together with Mari Izzard and Edward Easton, she worked on The Garden Centre, a BBC Radio Wales comedy project.
The sitcom was broadcast in 2023. Its setting provided an everyday environment that could support unusual characters and comic situations. Lowri and Mari were involved as both creative contributors and performers, giving them the opportunity to combine their acting experience with their developing writing work.
Radio comedy requires a different style from television. Without visual storytelling, characters must be established through dialogue, vocal performance, timing, and sound. Lowri’s experience as both an actor and voice artist makes this format particularly relevant to her broader career.
The Garden Centre also demonstrated that the sisters were not limited to a single writing project. After developing material for Sky Comedy Rep, they continued exploring new ideas through BBC Radio Wales.
Their comedy work received further recognition when they were shortlisted for the BBC Comedy Collective in 2023. They also became involved in the writers’ room for What Just Happened?, another BBC Radio Wales and Little Wander project.
These opportunities suggest a career that is developing in several connected directions. Lowri can perform material created by other writers, but she can also help build new characters and stories herself.
Television Work Beyond Her Major Roles
Although Hidden remains the screen role most closely associated with her career, Lowri has appeared in several other British television productions.
Her television credits include appearances in Casualty and Doctors. Both programs have long histories in British television and regularly feature guest performers in self-contained or continuing storylines. These roles allowed her to work within established television productions while expanding her screen experience.
She has also been credited in Sitters, a BBC Three production. Another credit connected with her screen career is Doctor Who, one of Britain’s most internationally recognized television franchises.
These appearances are useful when looking at her career as a whole because they show that it cannot be defined by one program. Her work includes Welsh-language and English-language projects, drama, comedy, film, radio, theatre, and voice performance.
That variety can be especially valuable for a working actor. Television opportunities can change quickly, and performers who are comfortable across several formats often have more creative routes available to them.
Lowri Izzard’s Creative Range
One of the most distinctive features of Lowri Izzard’s career is the number of creative disciplines she has explored. Acting may be at the center of her professional background, but it now sits alongside writing and voice performance.
Her dramatic work has included crime television, while her film career has included comedy and Welsh historical drama. Her theatre background has required live performance skills, and her later writing projects have introduced another side of her work.
This range does not mean that every part of her career exists separately. Many of the skills overlap. Acting experience can help a writer understand how dialogue sounds when spoken aloud. Theatre training can improve timing and physical awareness. Voice work can strengthen control over tone and character. Writing can give an actor a deeper understanding of story structure.
Her bilingual ability also adds another dimension. Being able to work professionally in both Welsh and English gives her access to productions created specifically for Welsh audiences as well as projects reaching viewers across the United Kingdom.
Rather than moving away from acting, her writing work appears to have broadened the type of creative career she can build.
Writing Characters With an Individual Voice
Lowri and Mari Izzard have shown particular interest in character-led comedy. That approach places personality at the center of a story instead of treating characters simply as ways to deliver jokes.
It is a style that suits performers who also write. Actors spend considerable time thinking about motivation, rhythm, behavior, and relationships. Those same questions can become useful when creating original comedy characters.
The sisters have also expressed an interest in unconventional protagonists. This can create stories around people who might not normally be placed at the center of mainstream comedy.
Their Welsh background also provides a cultural perspective that can influence their storytelling without limiting their work to one type of audience. British comedy has a long tradition of strong regional voices, and newer writers continue to expand the range of characters and communities represented.
For Lowri, writing therefore appears to be more than a side project. The commissions, development programs, radio work, and writers’ room experience show a serious effort to build skills within professional comedy.
Lowri Izzard’s Current Creative Direction
Lowri Izzard’s recent professional path suggests that she is building a career that combines performance with original storytelling.
The development of Spoffin after Sky Comedy Rep was particularly important because it gave Lowri and Mari the opportunity to continue working on material that began in a theatre setting. Moving a project toward screen development requires writers to rethink how a story works visually, how episodes may be structured, and how characters can develop over a longer format.
Their radio work has given them another environment for testing characters and comedy. Writers’ room experience has also allowed them to contribute within a collaborative setting rather than working only as an independent writing team.
At the same time, Lowri continues to have an established background in acting. Her experience across television, film, theatre, and voice work gives her several possible directions for future projects.
There is no need to predict exactly where her career will go next. What can be said from her existing work is that she has developed beyond a single acting role. Her professional identity now includes performer, voice artist, and writer.
For audiences who first discovered her through Hidden or Brian and Charles, her comedy-writing work offers another side of her creative career to follow.
Final Thoughts
Lowri Izzard has built a varied career across Welsh and British entertainment. From serious television drama to independent film, theatre, radio, voice performance, and comedy writing, she has shown an ability to work comfortably across different formats.
Her partnership with her twin sister Mari has become an especially interesting part of that story. Projects such as Spoffin and The Garden Centre have allowed the sisters to move from performers into original comedy creators, while professional development opportunities have given their writing greater visibility.
Lowri’s career is still developing, which makes it important not to exaggerate what is publicly known about her future projects or private life. Her verified professional record already provides a strong picture of an artist whose work extends far beyond one television character.
