10 Weird Things You Won't Believe Actors Did After Filming

10. The Rock Pushed Himself To Black Out With Real Chains... Eight Times! - Hercules

It has to be said that you usually wouldn't be too quick to class Dwayne "The Rock" Johnson as an actor who is deeply committed to legitimately living and breathing the same experience as the characters he plays on the big screen. After all, if that was consistently the case, he'd have likely sincerely fallen off a skyscraper and/or been made roadkill by a genuine raging bull by now.

However, a few years before those aforementioned big screen moments came about, Rocky was seemingly determined to show he meant business on the set of 2014's Hercules when sharing the screen with the likes of John Hurt and Ian McShane. So, instead of using fake chains for a scene that saw his titular character break free from imprisonment and roar his name aloud, Johnson had the real thing installed on the day.

The only issue with this was the fact that his monumental build-up of adrenaline from the roar, and lack of give, instantly resulted in him blacking out seconds after the shot was in the can. But no matter, Johnson well and truly lay in his bed and performed the scene a whopping eight times in total.

That's a lot of fainting.
