Stunt double

Actors aren't really superheros or experienced motorcyclists or black belts in karate. They have stunt doubles who jump off buildings, get in fights, and outrun the police for them.

At right, stunt man Matt Taylor filmed a motorcycle chase sequence for the film "The Surrogates" on Munroe Street in Lynn.
