A spokesman for Broadway's most expensive show says the actor was injured during yesterday night performance, which was immediately stopped. The actor, Daniel Curry, had a serious leg injury.
Fire officials said they responded to treat a man whose leg got caught in equipment backstage.
Curry was one of several actors who play Spider-Man during each performance, leaping into the audience and swinging over the orchestra.
The musical "Spider-Man: Turn Off the Dark" has become one of Broadway's biggest hits after a difficult start, with six delays in its opening night, injuries to fellow actors, the firing of the show's original director and critical drubbing.
A lead actress, Natalie Mendoza, suffered a concussion during the first preview performance. A stuntman, Richard Kobak, sued the producers, saying he suffered a concussion, whiplash and two holes in his knees.
