7. Carl Weathers Stormed Off Set After Dolph Lundgren Hit Him For Real - Rocky IV
We all know that Rocky IV's iconic battle between Apollo Creed (Carl Weathers) and Ivan Drago (Dolph Lundgren) concludes with Creed dying in the ring, but during shooting for the scene, things got a little too close for comfort for Weathers.
While sparring, Lundgren got a little too into the role of the Russian destroyer and ended up hurling his co-star across the ring, prompting Weathers to walk off the set, call his agent and declare that he was quitting the movie.
Production was shuttered for four days while writer-director-star Sylvester Stallone attempted to coax Weathers to return, which he eventually did after Lundgren agreed to cool his method acting down a tad.
