5. Mickey Rourke in The Wrestler
It’s only fair; actual wrestlers pull shit 10 times worse than pretty much everything I’ll mention today – the least Mickey Rourke can do is get in on the action. During the scene where Rourke’s character
gets bloodied because wrestling is totally real makes himself bleed – the idea is that he hides a little razor blade on his body to cut himself with to simulate an injury.
While director Darren Aronofsky did have a prosthetic forehead created for the gag, the actor decided to fake faking the injury with real razors with a real razor. Did that make sense? He cut himself in real life to pretend to be someone cutting himself in a movie to pretend to get cut in a wrestling match. It’s simple. The point is that he really did it.
