10 Hilarious Actor Pranks (That Went Too Far...)

10. The X-Men Cast Shot Each Other - X-Men: Days Of Future Past

The cast assembled for Matthew Vaughn’s X-Men contained a nucleus of talent that most could see were going places. By the time Days Of Future Past rolled around, the clan were bonafide box office. If one of these megastars was to get injured, the costs of scheduling reshoots alone would be the kind of headache a big studio, like FOX, could do without.

With that in mind, you have to wonder whose idea it was to allow James McAvoy and Michael Fassbender to include BB-gun Wars in their downtime between scenes.

McAvoy remarked how "you were probably going to get hit in the face. And probably get your skin broken," which sounds like a make-up nightmare, frankly.

Some level of on-set shenanigans is almost always guaranteed, but these actors are responsible for the livelihoods of all the men and women on set, doing their jobs and providing for their families. It would only be a matter of time before an actor would go down with an injury through something as juvenile as freak toy gun accidents and the financial hit on the studio and crew would be embarrassing.

Luckily no-one was severely hurt, but it could very easily have been a lot worse.
