A veteran stage performer in his native Canada, Kevin McNulty has carved a niche for himself in the United States as a solid character actor in a career spanning everything from sci-fi to big-budget Hollywood films to docudrama TV movies. McNulty began acting in regional Canadian stage productions in the early 1980s, and by the end of the decade, he had landed small roles in several low-profile American films. In 1990, he appeared in the action-packed drama "Bird on a Wire," about an FBI informant who goes on the run after his cover is blown, later portraying a distant father in the fantasy film "The Neverending Story III." During the '90s, McNulty specialized in tearjerker cable dramas, most memorably appearing in the cult classic "Mother, May I Sleep With Danger?," which starred Tori Spelling as a college student who falls in love with a mysteriously perfect stranger. McNulty, who continued to appear in films like the deliberate B-movie thriller "Snakes on a Plane" and the superhero action film "Fantastic Four," also starred in numerous TV series during the 2000s. He eventually landed a recurring role on the Canadian legal drama "Da Vinci's Inquest," which detailed a coroner's crusade for justice, and he also appeared as a doctor on the sci-fi series "Stargate SG-1" and as a polygraph administrator on the critically acclaimed "Battlestar Galactica."
