While at UCLA, he was a member of Tim Robbins's acting troupe and it was through this collaboration that led to his 1992 film debut in Bob Roberts (1992). Although he was just a background voice in his first film, Jack's appearances in such television shows as The X-Files (1993), his breakthrough performance in High Fidelity (2000), and his rock-comedy band, Tenacious D, have created an ever-growing cult following.
