Chase Armitage, has been cast as a Snatcher for Deathly Hallows.  On his website he says:

My great passions come from anything with a challenge, I have always loved to put myself up against the odds, to try something a little different, I guess this is how I found myself in the disciplines of Parkour, Free-running and Martial-arts. These arts have always been with me, as a young boy I was always jumping, climbing, and imitating the action I saw in such Jackie Chan films. After training for a few years and hitting the age of college, I found myself interested in filming and editing my action material, so I got deeper into learning and the development of filming and editing.

Thanks SS
