Stunt doubles are a vital part of the entertainment industry. Stunt men and women who are trained in their field, are made to look enough like the actor they are doubling for.
This way, the actor who is, harsh as it is to say, more valuable, in the context of the film or show, won't get hurt.
However, sometimes a suitable stunt double simply cannot be found. Such is the case with Verne Troyer, the actor who plays Mini-Me in the "Austin Powers" franchise.
Troyer, who stands at 2 feet 8 inches tall does all his own stunts because it is extremely difficult to find a stunt double the same size as him.
However, Troyer has worked as a stunt double. One of his first ventures into acting was when he was the stunt double for a baby in the 1994 film "Baby's Day Out."
