I saw this documentary about a group of french guys that would do random stunts across the city with anything they could find. It was a sort of urban gymnastics. Can’t remember the name it goes by. Any Help?
District B13, the movie with David Belle, is now out on DVD in the U.S. There are spectacular parkour scenes in it - all real, no CGI. It’s also one of the tiny number of action films these days worth watching. Definitely recommended.
