At the end of a long alleyway off West Street in Greenpoint, Brooklyn, sits Bob Cotter's playground. Four years ago Cotter opened Hollywood Stunts, a training facility where professional stuntmen come to hone their skills and first-timers can try their hand at the incredible feats they had only seen in the movies. Trampolines and soft mats line the converted warehouse's perimeter. Bodies fall from tremendous heights onto the huge blue air bag below. "We're going to be setting some people on fire for some Australian Reality show," Cotter informs his instructors casually. This isn't your average day job.
