William James Nesbitt OBE (born 15 January 1965) is an actor and television presenter from Northern Ireland.
From 1987, Nesbitt 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). He got his breakthrough television role playing Adam Williams in the romantic comedy-drama series Cold Feet (1997–2003, 2016–present), which won him a British Comedy Award, a Television and Radio Industries Club Award, and a National Television Award.
Nesbitt's first significant film role came when he appeared as pig farmer "Pig" Finn in Waking Ned (1998). With the rest of the starring cast, he 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.
