Robert Patrick

If Patrick had passed on the part of a killer cyborg in 1991's Terminator 2: Judgment Day, his career might have been quite different. His steely blue eyes, chiseled physique and menacing vibe were so convincing that he spent the next decade playing bad guys in big flicks, with B-list fare offering him a wider variety of roles. Yet true fame eluded him until he signed on to The X Files in 2000. Although the long-running show only lasted two more seasons, Patrick was no longer "that guy" from T2 and his change in status showed in the kinds of projects he was offered (Ladder 49, Walk the Line). But the veteran actor continued to have a journeyman's attitude toward his work, signing on to two low-rent projects for every one A-list gig. In 2006 he returned to series television as a military man in The Unit.
