Jan Chappell is an English actress best known for her iconic portrayal of Cally in the first three series of the classic science fiction series Blake's 7, a role that has cemented her status as a beloved figure in British cult television. Born Janet Victoria Chappell in Brixton, London, she trained at the prestigious Royal Academy of Dramatic Art before launching a career that has spanned stage, screen, and audio drama for over five decades. Her versatility as a performer has allowed her to move seamlessly between period dramas, contemporary thrillers, and avant-garde theatre, making her one of the more quietly accomplished character actors of her generation.

Chappell’s early screen work included a memorable appearance in The Devils, directed by Ken Russell, as well as a role in The Virgin and the Gipsy. She also appeared in the film Low Tide and much later in Basic Instinct 2, where she played a random solicitor, a role that delighted Blake's 7 fans who were pleased to see their beloved Cally pop up in a Hollywood sequel. Her television credits from this period are extensive and include landmark productions such as The Naked Civil Servant and Reilly, Ace of Spies, as well as series like Mr. Palfrey of Westminster, Inspector Alleyn Mysteries, The House of Eliott, Boon, Lovejoy, Pie in the Sky, Holby City, New Tricks, Spooks, and Rosemary & Thyme. She also appeared in the direct-to-video Doctor Who spinoff Shakedown: Return of the Sontarans in 1995, further solidifying her connection to science fiction fandom.

Alongside her screen work, Chappell has maintained a distinguished career in theatre. She has performed in Nottingham for Roland Joffe, in Leicester and Stoke-on-Trent with Peter Cheeseman, and enjoyed three seasons with the Royal Shakespeare Company, including a notable production of Richard II starring Ian Richardson and directed by John Barton. Her repertoire includes plays by Peter Handke, Snoo Wilson, Arnold Wesker, Caryl Churchill, and Howard Barker, as well as Mike Bartlett’s My Child, directed by Sacha Wares at the Royal Court Theatre in London. She appeared in three of the Tribunal plays for Nicolas Kent, including The Colour of Justice, about the Stephen Lawrence Inquiry, at the Tricycle Theatre in Kilburn. She also played Presiley Baxendale in Half the Picture, a play about the Scott Inquiry into Arms for Iraq, and portrayed human rights lawyer Gareth Peirce in Guantanamo, which transferred to London’s West End and was performed in the Raeburn Building (US Congress) in Washington, D.C.

From 1999 to 2000, Chappell expanded her work into audio drama, appearing in three episodes of MJTV’s original sci-fi CD series Soldiers of Love as Sharliken and Mom. In April 2010, she appeared at the Royal Exchange Theatre in Manchester in A Comedy of Errors, directed by Roxana Silbert of Paines Plough and the Royal Shakespeare Company. With a career defined by both her iconic television role and her extensive stage work, Jan Chappell remains a respected and enduring figure in British entertainment, continuing to take on challenging roles that showcase her range and dedication to her craft.
