Yeah! The star of District B13 is David Belle, the guy who started Le Parkour. There's a pretty hefty philosophy behind it, of overcoming obstacles, of minimizing energy usage, and as such, true Parkour doesn't incorporate things like flips (because flips are never part of the energy-optimal way to get from point A to point B.)
Then there's freerunning, which is basically parkour minus the philosophical rigidity. Sebastien Foucan founded that one, and it started out much like parkour but eventually integrated stunts and focused more on the aesthetic, and so they diverged.
Sebastien Foucan is the guy at the beginning of Casino Royale, the one Bond chases through the opening scene. He's no slouch either.
