Son of British actor Charles Lloyd Pack, Roger Lloyd Pack graduated from the Royal Academy of Dramatic Art in London. His first onscreen credit came as a 21-year-old, when he appeared fleetingly in an episode of the classic British spy series "The Avengers" in 1965. Along with frequent appearances on BBC programming throughout the '70s, Pack became a familiar face in England after being cast as the bumbling Trigger in the long-running sitcom "Only Fools and Horses " in 1981. American audiences were introduced to Pack in 1994, when he appeared in a small role in the hit supernatural thriller "Interview with the Vampire: The Vampire Chronicles." That same year, he joined the ensemble of another BBC comedy,"The Vicar of Dibley," as a slovenly farmer; like "Only Fools and Horses ," the show enjoyed a long run into the 2000s. Pack hit the American mainstream again in 2004, when he appeared opposite Reese Witherspoon and Gabriel Byrne in the period drama "Vanity Fair." This big-budget production was trumped when he joined Daniel Radcliffe and company in the fourth "Harry Potter" installment, "Harry Potter and the Goblet of Fire," as wizarding bureaucrat Barty Crouch. Pack then secured a main role on "The Old Guys," as one of a pair of over-the-hill roommates, although the comedy failed to match the success of his previous BBC works.
