Can you imagine how awesome it would be to have someone who looks just like you step in and take over when something's a bit too challenging? Such is the life for actors like Selena Gomez and Taylor Lautner.

When a movie requires some type of crazy trick, more times than not a trained stunt double will step in and perform it so the actors won't get hurt. Since stunt doubles are really only used for scenes that involve fast-paced action, like motorcycle riding or cliff jumping, we usually don't even realize it's a different person!

For instance, did you know Robert Pattinson had a stunt double for all of the Twilight films? While the actor was able to do a lot of his own minor stunts, some of the fight scenes (like the epic one at the end of the first movie) were just too intense for him.

"Robert Pattinson is an amazingly humble person and a very hard worker," Rob's Twilight stunt double Paul Darnell said. "He works very hard and shows up to every rehearsal. The last battle scene in Twilight was very intense — many of the stunts involved hard hits with wires and crashes… Without risking personal injury to Rob, I ended up doing the majority of stunts in the final battle."
