Kiefer Sutherland and the actors who played the other motorcycle-riding vampires in The Lost Boys did their own stunt work during production.
Upon hitting the obstacle, the actor was thrown off the bike and broke his right wrist in three places.
After that a special cast had to be created for Sutherland, who also had to start riding a bike with the brake and clutch on the left side because of the injured wrist.
And, though this makes all the classic motorcycle scenes look even more badass, there were some drawbacks, like the time Sutherland broke his wrist while trying to impress a girl walking along the Santa Cruz boardwalk.
