7. Michael Edwards - Old John Connor In Terminator 2
The Role: The opening scene of Terminator 2, Edwards plays a middle-aged John Connor, complete with a scar across his face, for a brief few seconds.
Why It's Amazing: Edwards doesn't get to say a single word and has little time to establish a screen presence, but the totally badass looked caused many to hope that he might end up in a later Terminator movie (they went for Christian Bale instead, unsurprisingly).
What Happened?: Little is known about Edwards post-T2. He had a few tiny extra roles in the likes of Frasier before disappearing off the Hollywood map completely.
