Stephen Mangan

Stephen Mangan is an acclaimed actor, writer, and presenter whose work across stage and screen has made him a household name.

Stephen Mangan stars in the major 2026 West End revival of Florian Zeller’s comedy The Truth at the Apollo Theatre in London.

A graduate of Cambridge University and RADA, his career is defined by a rare ability to blend razor-sharp comic timing with profound dramatic vulnerability.

He is best known for his television roles including 5 seasons of Episodes, opposite Tamsin Greig and Matt LeBlanc, The Split with Nicola Walker, BAFTA winning sitcom Green Wing, I’m Alan Partridge and Free Agents.

Most recently, Stephen starred as Nick in the world premiere of Unicorn at the Garrick Theatre. Reuniting with his The Split co-star Nicola Walker, Mangan delivered a “wonderfully believable” performance in Mike Bartlett’s explicit and funny dissection of modern relationships. His portrayal of a man navigating the complexities of a “throuple” was praised for its clinical precision and quintessentially British self-deprecating discomfort.

Stephen made his breakthrough television performance as ‘Adrian Mole’ in the BBC series Adrian Mole: The Cappuccino Years. This was closely followed by his appearance in Channel 4’s Sword of Honour alongside Daniel Craig and as Dan Moody in I’m Alan Partridge.

Stephen Mangan’s Versatility

Whether he is navigating the complex legal drama of The Split or the absurdism of Green Wing, the truth about Stephen Mangan is that he is at his best when deconstructing the masks we wear in polite society. His recent work in Unicorn proved once again that he is a master of the “long-married” dynamic, often portraying characters who struggle to express their deepest desires.

Theatre Highlights

Unicorn (2025): Originated the role of Nick opposite his split co-star Nicola Walker in Mike Bartlett’s biting new play about intimacy and honesty.
The Resilience of a Leading Man: While every actor faces the occasional “turkey,” Mangan’s performance in the 2019 adaptation of The Man in the White Suit was a masterclass in professional grit. Despite the show’s early closure, Mangan was hailed by critics for his “baffled charm” and physical comedy, proving he could hold an audience even when the material faltered.
The Norman Conquests: His performance at The Old Vic (and subsequent Broadway transfer) earned him a Tony Award nomination and established him as a premier leading man.
Jeeves and Wooster: Showcasing his comedic dexterity, Mangan led the Olivier Award-winning Perfect Nonsense at the Duke of York’s Theatre.
