Jackie Chan
Beloved Hong Kong film star and martial artist Jackie Chan actually began his acting career as a child, appearing in films as early as five years old. His most famous work as an extra is inarguably his brief appearances in Bruce Lee’s Fist of Fury and Enter the Dragon. Jackie is also unsurprisingly credited as a stunt performer in these films. His impressive performances in these minor parts would then lead to the actor getting fight choreography work for director John Woo (which in turn led to higher profile roles).
