(Newser) – The latest trouble for Spider-Man: Turn Off the Dark: An actor in the Broadway musical was injured during last night's performance, leading the show to be halted. Fire officials said they responded to treat a man whose leg got caught in equipment backstage. The actor, Daniel Curry, had a serious leg injury; he is one of several actors who play Spider-Man during each performance, leaping into the audience and swinging over the orchestra.

Actors' Equity Association, a labor union that represents actors and stage managers, issued a statement saying it is "deeply concerned about the Equity member who was injured in the Thursday evening performance" and "has initiated an investigation into the situation, working closely with its members and the representatives of the production." Despite the offstage drama, the $75 million show—Broadway's most expensive—has become one of Broadway's biggest hits. Other problems included six opening night delays, the firing of the show's original director, bad reviews, and injuries for three other actors. (Read more Spider-Man musical stories.)
