Claire Lams is a British actor whose career has grown through theatre, television, film and radio. She is best known as Ginny Potter in the London production of Harry Potter and the Cursed Child. Her work reaches much further, with credits at the National Theatre, Royal Court Theatre, Hampstead Theatre, Broadway and major British television programmes.
Claire Lams joined the Cursed Child company from 15 October 2024, taking over Ginny Potter at the Palace Theatre. The part brought her to a wider international audience after more than two decades of professional work. Her career includes classical plays, new writing, comedy, drama, family theatre, audio drama and screen acting.
Claire Lams’ Education and Early Career
Claire Lams trained at Queen Margaret’s College in Edinburgh. Her casting CV records student productions between 1998 and 2001, including Juliet in Romeo and Juliet, Emily in Our Town, the Abbess in The Comedy of Errors, Angustias in The House of Bernarda Alba and Cecily in The Importance of Being Earnest.
Her earliest professional stage credit is The Dice House in 2002. She then worked with the Birmingham Stage Company, Royal Exchange, West Yorkshire Playhouse, Stephen Joseph Theatre and National Theatre. These early roles built a strong foundation in modern drama and classic writing.
Early Theatre Foundations
From 2003 to 2010, the actor developed a varied stage career. Her work included The Happiest Days of Your Life, Coming Around Again, Huddersfield, Fields of Gold, Soap, Citizenship, Chimps, Presence, Fabulation and Faustus. At the National Theatre, she worked in The Miracle, DNA and Baby Girl.
This period showed her ability to move between comedy, serious drama, new writing and large-scale theatre. The range of these productions remains central to her professional identity and helped her build strong links across the British theatre industry.
Claire Lams as Ginny Potter
The role of Ginny Potter is now one of her most recognisable performances. The West End production follows Harry, Ginny, Ron and Hermione nineteen years after the original story, as their children begin their Hogwarts journey. It explores parenthood, family pressure, friendship and the challenge of understanding a child.
In interviews, she has described Ginny as a working mother who edits the sports pages of the Daily Prophet. She sees the character as a practical, loving parent supporting a child who feels different. Her favourite part is the family dinner scene, which shows the characters together in an ordinary family moment.
Bringing a New Ginny to the Stage
Her interpretation focuses on the adult side of the Wizarding World. She has said that the play is not only about spells and spectacle; it is also a human story about parents trying to do the right thing. This gives Ginny emotional depth beyond her history with Harry.
The production lets her combine natural dialogue with physical theatre, stage movement and live effects. Her background in serious drama and comedy suits a role balancing warmth, humour, tension and magic.
A Major Theatre Career
One of her biggest stage achievements came with One Man, Two Guvnors. She played Pauline Clench in the National Theatre production, the West End transfer and the Broadway production at the Music Box Theatre in New York. The comedy gave her international theatre experience alongside James Corden and other leading performers.
Claire Lams later played Lisa in Routes at the Royal Court, the Queen in The Little Mermaid at Bristol Old Vic and Elizabeth in The King’s Speech at Chichester and Birmingham Rep. Her credits also include Rita in Educating Rita, Ana in While You Lie, Evelyn in Absent Friends and Debbie in The Spies in Room 502.
Notable Recent Stage Work
Her later theatre work includes Stephanie in Kiss Me, Louisa in The Lottery of Love, Kimberly in Paradise, Nadia in Rust, Candida in Candida, Yasmin in The Climbers and Mrs Hanratty in Mates in Chelsea. She has worked at Hampstead Theatre, Trafalgar Studios, the Orange Tree Theatre, Bush Theatre, Theatre by the Lake and the Royal Court.
Kiss Me was especially personal to her career. Writer Richard Bean had worked with her before and created Stephanie after conversations about the shortage of strong parts for women. She described the rehearsal process as intense but joyful because the production had only two actors.
Television and Film Work
Her television career includes single-episode roles and larger parts in British dramas. She played Andrea Ellis in Showtrial, Tina Hemmings in Cobra, Angie Phelan in Trigger Point and DC Julie Dennison in The Salisbury Poisonings.
Other television credits include The Perfect Couple, Casualty, Call the Midwife, Humans, The Wrong Mans, Silent Witness, Obsessed, Random, Doctors, The Bill, Holby City, The Brief and EastEnders. Her official production biography also names Traitors, Trauma, The Spa, Outnumbered, Extras and Border Crossing.
Her film work includes The Duke, Pumpkinhead 4: Blood Feud, Southwark the Movie and Danielle. She has also worked in short films such as Beyond the Blade, Tease and Today’s Date, plus the film-school project Sputnik. Other screen credits include Stop Dead, Ma’am, The Everlasting Club and The Ivory Wife.
Radio and Audio Performance
Radio is another part of her work. She played Dora Sunnyside in the BBC Radio 3 production of The Octoroon and has credits in The Family Business and the audio drama 11 Minutes Dead. Audio performance requires vocal control, timing and imagination, skills that also support her stage work.
Skills Beyond Acting
Her casting CV records a height of 162 centimetres, hazel eyes, auburn hair and a playing age of 35 to 40. The playing-age figure is used for casting and should not be confused with her real age.
She speaks English, French and Swedish, and can perform London, Cockney, Scottish, Yorkshire, Irish, French, German, Australian and American accents. Her additional skills include singing, oboe, recorder, ballet, tap, ballroom, salsa, contemporary dance and professional cycling.
Her performance training also covers actor-musician work, circus skills, aerial work, clowning, juggling, trapeze and stage combat. She has experience with climbing, fencing, horse riding, scuba diving, skiing, swimming, yoga, Pilates, running and triathlon.
