This is the clip of David Belle doing parkour in the french movie Banlieu 13 (District 13) which also stars cyril raffaelli who was in kiss of the dragon with jet li. David Belle, according to what I've read was one of the founders and earliest practitioners of parkour along with the likes of Sebastien Foucan who is the founder of free running, which is similar to parkour with a slight difference.
Where parkour is simply focused on moving as efficiently as possible from point A to point B with as little tricks and unnecessary movements as possible, free running incorporates the same concepts of useful movement along with inclusion and openess to free expression of the free runners allowing them to perform tricks and aesthetically pleasing moves whilst trying to move quickly between locations
