EDIT:The link brought up random comments not the one i read. Basically he said that the interwiews were boring and the people being interviewed were pompus. Also that basically the guys were trying to make parkour seem more than just grown men playing kids games.
Also this is the plot summary of it.
http://www.imdb.com/title/tt0435675/plotsummaryhere is a alittle part of it. "Free Running, or Le Parkour, involves literally leaping from roof to roof in a death-defying, yet beautiful, series of jumps, slides and somersaults. It is a discipline combining an extraordinary athleticism and lack of fear - created by Sebastien Foucan and his friends"
Now granted he mentions free-running but it also mentions parkour. Also it's some guy's synopsis not someone who actually had something to do with it. The reason why i am bringin this up is because that is a really bad first impression of what parkour is. Also sorry if this is old. If it is feel free to close the topic.
