Well, seeing as how it's voluntary, I don't really see a problem.

Perhaps Casino Royale made people believe in the upside.

I just noticed Casino Royale's intro. is up there too. Ha.

I found this in a BBC NEWS article:

>>

Two documentaries followed - Jump London (2003) and Jump Britain (2005) - featuring Sebastien Foucan, who had practised with Belle growing up in Paris.

Although the pair have gained global stardom - appearing in lucrative advertising campaigns and films - they stress the inner spirit of Parkour is not about financial gain or prestige.

"I always thought of Parkour as an art," said Foucan, who is to make his acting debut in Casino Royale as a terrorist hunted down by Daniel Craig's James Bond character.

"When I practise my art I feel a real connection between my body, spirit and my environment," he told the BBC News website.

The Bond chase sequence is being billed as one of the most ambitious in the history of the action series but Foucan is quick to point out the dangers of reckless copycat stunts.

"I never push my limits. I'm now lucky to practise my high-level moves with professional safety people around me.

"Parkour is not about looking for danger and impressing people. It's not about jumping gaps; it's about movement and flow - never forget the fundamental basic moves," he said.

David Belle will be starring as one of the villains in the upcoming Bond flick "Casino Royale." There is a chase scene in which Belle and Bond go tearing across the city and Belle uses Parkour moves throughout the sequence.

Sorry, I'm unable to provide a citation for that, but I'm pretty certain of it. Can anyone back me up?
