10 Strangest Reasons Actors CLASHED On Set

10. Sylvester Stallone Makes Dolph Lundgren Cry Over Grandmother Remark - The Expendables

It didn't matter that the pair had starred alongside each other in one of the greatest boxing flicks of all time and had been pals ever since, that still couldn't stop Sylvester Stallone from firing a rather bizarre insult his co-star's way when directing Dolph Lundgren on the set of the first Expendables feature.

When recently appearing on In Depth With Graham Bensinger (via Variety), Dolph revealed that Sly made him perform a scene "20 times", all whilst being quite "harsh" on the towering thespian and yelling at him "in front of the whole crew."

But the words "‘My grandmother could do it better than that. What the f***, what are you doing?" were what ultimately pushed Lundgren to tears before the cast and crew took their lunch break.

And it was that bizarre outburst from Sly that left the Ivan Drago and Gunner Jensen actor telling his wife down the phone that he was going to knock the stuffing out of this particular Expendable if he dared say another word to him.

Likely sensing he'd gone too far with his strange grandmother remark, the "crazy Italian", as Lundgren put it, soon apologised for his aggressive directing style post-lunch.
