Jackie Chan has shown near super-human abilities in his more than 100 films, and yet he tells the BBC he wishes for super powers like Spider-Man or Superman to help tackle the world's problems.

The martial arts star was among high-profile goodwill ambassadors marking Unicef's 70th anniversary in New York this week. The BBC's Laura Treveylan caught up with him to talk about Unicef and his work with children with HIV and Aids.

Filmed by Stephen Greaves. Edited by Bill McKenna. Produced by Mat Morrison.
