Kris Marshall burst onto the scene in 2000 when he appeared in the hit BBC sitcom My Family. Marshall played Nick Harper, the dim-witted, lazy eldest son of Ben and Susan Harper, played by Robert Lindsay and Zoe Wanamaker respectively. Marshall’s character often flitted between jobs – one episode he’d be a stuntman, the next a ‘gorilla-o-gram’. Marshall remained in the series for five years before leaving in 2005.
During his time in My Family, Marshall appeared in the film Love Actually. He played the character Colin who decides British girls are not for him and he would have better luck with love on the other side of the Atlantic. While in Wisconsin, Colin is seduced by three American girls in a bar and, according to IMDb, Marshall waived his fee for filming these scenes because "he had such a great time”.
Upon leaving My Family in 2005, Marshall became recognisable as the face of television adverts for BT. Over the course of six years, the adverts told the narrative of his character Adam meeting, falling for and eventually marrying Jane, played by Esther Hall.
Marshall’s theatre credits include Moliere's The Hypochondriac. Marshall starred alongside Henry Goodman in a new version of the play by Richard Bean at the Almeida Theatre in 2005. He went on to appear in The Revenger’s Tragedy at Southwark Playhouse, Treats at the Garrick, and Fat Pigs at Trafalgar Studios. While preparing for Fat Pigs, Marshall was hit by a car as he enjoyed a night out with friends in Bristol. He suffered head injuries and, after making a full recovery, began in Fat Pigs three weeks later than scheduled.
Marshall also plays DI Humphrey Goodman in the television series Death in Paradise. He replaced Ben Miller as the lead role and starred in the show for four series. At the same time, Marhsall was embarking on his most recent theatre project. He played Kelvin in Lindsey Ferrentino’s play Ugly Lies the Bone at the National Theatre. The play was about a soldier returning from her third tour of Afghanistan and uses virtual reality to pioneer her therapy. In October 2017, Kris Marshall played John Williamson in David Mamet’s Glengarry Glen Ross
