can't find it online, but there's a story out there about Burt Reynolds and Rip Torn as struggling actors.

Reynolds of course is the more confident, if less talented, one. he talks Torn into going to an audition with him.
Torn kills, but walks out. Burt gets him to come back, but Torn will only take the part if Burt gets one, too. pretty ballsy.

it's a deal - and the rest is history, for both.
