Wait, wait... are we voting for the star themselves or for the character they played in the movie? Because quite frankly, I wouldn't want any of those characters to have my back... I'd rather have someone like Sonny Puzikas [http://www.spike.com/full-episode/green-beret-vs/32039] or Snake Blocker [http://www.spike.com/full-episode/apache-vs-gladiator/31444] on my side. You know... REAL fighters.
Out of the choices, (and assuming I'm voting for the person, not the character), I'd have to vote for Jet Li. The dude is a real, legitimate asskicker. I'm sorry, but none of the others (except maybe Steve Austin, if you want to count him) can make that claim. (but come on... "Ying Yang"? *shudder*)
