William James Nesbitt, (born 15 January 1965) is an actor and presenter from Northern Ireland. Born in Ballymena, County Antrim, Nesbitt grew up in the nearby village of Broughshane, before moving to Coleraine, County Londonderry. He wanted to become a teacher like his father, so he began a degree in French at the University of Ulster. He dropped out after a year when he decided to become an actor, and transferred to the Central School of Speech and Drama in London. After graduating in 1987, he spent seven years performing in plays that varied from the musical Up on the Roof (1987, 1989) to the political drama Paddywack (1994). He made his feature film debut playing talent agent Fintan O'Donnell in Hear My Song (1991).
Nesbitt got his breakthrough television role playing Adam Williams in the romantic comedy-drama Cold Feet (1998–2003), which won him a British Comedy Award, a Television and Radio Industries Club Award, and a National Television Award. His first significant film role came when he appeared as pig farmer "Pig" Finn in Waking Ned (1998). With the rest of the starring cast, Nesbitt was nominated for a Screen Actors Guild Award. In Lucky Break (2001), he made his debut as a film lead, playing prisoner Jimmy Hands. The next year, he played Ivan Cooper in the television film Bloody Sunday, about the 1972 shootings in Derry. A departure from his previous "cheeky chappie" roles, the film was a turning point in his career. He won a British Independent Film Award and was nominated for the British Academy Television Award for Best Actor.
Nesbitt has also starred in Murphy's Law (2001–2007) as undercover detective Tommy Murphy, in a role that was created for him by writer Colin Bateman.

In 2007, he starred in the dual role of Tom Jackman and Mr Hyde in Steven Moffat's Jekyll, which earned him a Golden Globe Award nomination in 2008.
