Tall, rugged, and exuding an air of old school masculinity that has fallen out of fashion in modern movies, Scottish-born actor Graham McTavish has nevertheless found a place in action cinema. He is likely best known for his performance as the fierce dwarf warrior Dwalin in director Peter Jackson's epic fantasy "The Hobbit: An Unexpected Journey" (2012). But before landing that role of a lifetime, the biggest of his career, McTavish was already known to many science fiction and action fans for his prominent roles on the beloved British cult sci-fi show "Red Dwarf" (BBC Two, 1988- ), playing Warden Ackerman, and in Sylvester Stallone's ultraviolent war picture "Rambo" (2008), where he played the mercenary Lewis. He is also well known for his role as the Russian conspirator Mikhail Novakovich on the television show "24" (Fox, 2001-2010). But despite his frequent typecasting as an onscreen bruiser, the gregarious Scotsman always brings a little of his own colorful personality to his roles.
