9 Movie Extras Who Completely Ruined Their Scenes

9. Little Verne Needs To Pee

Some sterling detective work went into finding this now infamous clip from Back To The Future Part III - I'd like to say it was done by my hand and trap-like mind, but it wasn't. But we can all still enjoy it nonetheless.

Quite worryingly, the rest of the internet seems to be convinced that the little chap in the following clip is an incorrigible pervert, due to his cheeky groin pointing in the background as Doc Brown avoids telling Marty McFly quite how he managed to magic a ruddy great train time machine out of nowhere.

In reality, it is pretty obvious that Verne - played by young Dannel Evans - was merely in dire need of a bathroom break. Still, it's remarkably funny all the same.

8. Careless Stormtrooper

Probably the most famous clip in the history of the entire universe, and certainly the most infamous bit of Star Wars footage, the careless stormtrooper who banged his head in 1977's A New Hope has gone down in Star Wars folklore as one of the most visible and unintentional mistakes of the franchise. Still not as bad a mistake as casting Hayden Christensen.

Unfortunately, the hilarious head banger also allowed George Lucas to flex his "comedy" muscles in subsequent Star Wars releases - first making Jango Fett bang his head on a low doorway aboard the Slave I in Attack of the Clones and then adding a ridiculous sound effect to the original bump in the 2004 re-release of the original trilogy.

It no doubt took all of his beardy constitutions to stop him from adding a comical little Wah-Wah noise to the scene as well.
