Action superstar Jackie Chan has anointed his successor but with a stark warning about the future.

The popular BTV reality show The Disciple climaxed at the Badaling Great Wall, where the actor passed his kungfu crown to Jack Tu, a 24-year-old Chinese-American.

Chan, who produced the show, will teach his protege the art of international filmmaking, but he's already told him it won't be an easy ride. "You will have to face a lot of pressure being in the spotlight," he said, "because it is much harder being a kungfu star than just being on stage."
