Video: Matt Damon Shows You How To Fake Fight
Matt Damon had me cracking up this entire video! In his own words, action actors like to act like tough guys, but in all actuality, they're dancers more than fighters. Fight choreography is a lot more difficult to manage than you would guess. You have to make sure you aren't actually injuring the person you're fighting while at the same time making the action look passable enough to appear on film.
I'm sure occasionally someone catches a rogue punch, but after four Bourne movies, you'd have to imagine Damon is kind of a pro at this. He acts like one at least!
