Yep, that's Sebastien Foucan, one of the original founders of Parkour. Keep in mind that movies are required to cable and pad most movements for liability, but the reason he makes it look so smooth is that he would do the same without the cabling or padding...15 years or so of training will do that!
His website is
www.foucan.com , but it's being updated at the moment so it's of little use
