Professional skier, base-jumping extraordinaire, and now, movie star, JT Holmes is proud to add "stuntman in a major motion picture" to his already impressive repertoire.

JT and friends, who customarily practice wingsuit flying in mountain environments, were recruited by director Michael Bay to be a part of the new flick, Transformers III: Dark of the Moon. The boys were given clearance to jump in downtown Chicago; until this shoot, wingsuit flying had never been practiced in an Urban environment.

Check out the official movie trailer.
