I saw this a the local "art house" a month or so ago and really liked it. The two leads, Cyril Raffaelli and David Belle accomplish some amazing action scenes. Raffaelli is an incredible martial artist, and to appreciate David Belle's Parkour expertise (he is the founder of Parkour
), you really have to see it in action. He's definitely in the same category as Jackie Chan and I would say even ramps it up to the next level in certain sequences. His moves remind me a bit of Brandon Lee as well. I really want to get this one on DVD.
Here's a link to the trailer:District B13 Trailer
