Sam Huntington began acting when he was nine years old, as part of the children's theater which his mother ran. He made his professional debut in 1991, when he joined local group Peterborough Players in several productions. He wanted to take the plunge into acting immediately, but later decided to train first.
Huntington returned to acting in the late 1990s, appearing in films such as Detroit Rock City, Not Another Teen Movie and Superman Returns. He was also part of the short-lived comedy Cavemen, in 2007. Currently he stars as the werewolf Josh in the American adaptation of the British series Being Human.
Huntington is married to actress Rachel Klein, with whom he has one child.
