Stuntman sues over 'Spider-Man' injuries NEW YORK, April 7 (UPI) -- A former stuntman on the Broadway play "Spider-Man: Turn off the Dark" alleged failure to update computer software led to injuries in both his knees. Richard Kobak asked a New York court to compel the producers of the extravaganza to turn over documents about the computer that controlled the rigging used in the many aerial stunts that were a highlight of the show. Kobak contends the production crew never reprogrammed the computer to accommodate his weight after he hurriedly replaced Christopher Tierney, who was injured in a 30-foot fall while on stage in 2010. Kobak's petition indicates his knees took a beating from some 70 jarring landings on the stage. The stuntman alleged he also hurt his back and suffered a concussion when the rigging hurled him into a wall, The Hollywood Reporter said. The Reporter said the production company behind "Spider-Man" declined comment but noted Kobak was back to work on the Green Day musical "American Idiot."
