Named after the famed Dutch post-impressionist painter Vincent van Gogh, actor Vincent Kartheiser made his mark as a child actor with supporting roles in mostly family-friendly fare like "Little Big League" (1994) and "The Indian in the Cupboard" (1995). But as an adult actor, it was his performance as the ambitious, but amoral Pete Campbell on "Mad Men" (AMC, 2007- ) that transformed Kartheiser into a star. Prior to "Mad Men," the young actor established himself on the small screen with more mature roles, most notably in playing a homeless, drug-addled street hustler in Larry Clark's "Another Day in Paradise" (1998). Moving over to the small screen, Kartheiser spent three seasons on "Angel" (The WB, 1999-2006) playing Connor, the superhuman son of the series' titular vampire, which led directly to his better known role on "Mad Men," where his Pete Campbell used his cunning ambition to climb from account executive to partner of Madison Avenue advertising firm Sterling Cooper Draper Pryce. Because of the popularity of his character, Kartheiser landed substantial roles in films like "Rango" (2011) and "In Time" (2011), while maintaining his presence on "Mad Men" as the character everybody loved to hate.
