Who would win in a real fight?

If the objective of a fight to the death is to become dead, then Bruce Lee would be the winner by default.

Haha, Taylor Lautner. I think he'd sit this one out.

Let's see here...
Jean Claude now just stands on trucks moving backwards doing the splits. Loses.

Sly just uses his fists for boxing and he loses.

Jason talks tough but not a fighter. Lost.

Wesley has not been in fighting shape for years. Loser.

Jackie has to do a second take because he can never get it right the first time when he hurts himself. Out.

Keanu doesn't know any martial arts. Dead.

Taylor. Dunno him but I bet he loses.

Segal is out of shape, fat and slow. Loses.

Bruce is already dead.

Winner? Chuck Norris of course!

Jason Statham solely based on his

Keanu Reeves coz no one wants to hurt Keanu Reeves. And so it would end politely before it even began, likely with hand shakes.

I'm afraid most of these guys aren't actually trained in combat, just enough to look good on camera, so only someone like Bruce Lee might win.

Lautner. He has the speed and stamina on all these old folks, especially an advantage over Lee. Maybe I give Jackie Chan an edge since he is heavily trained.

Hand to hand?

I'd go with Bruce Lee from that crowd.
