AceShowbiz - The latest disaster for the "Spider-Man" musical, which saw an actor seriously injured on-stage during a preview performance, has been blamed on "human error". The beleaguered Broadway show "Spider-Man: Turn Off the Dark" has been blighted by a series of setbacks - previews finally began in November after months of problems and rigorous safety checks, but the opening show was halted throughout as stunts went wrong.

Producers then decided to push back the official opening until February to incorporate "new ideas", but another preview on Monday, December 20 ended in disaster as the show was cut short following a horrific accident. Stunt double Christopher Tierney was taken to New York's Bellevue Hospital for treatment after he tumbled from a platform above the stage. It was later revealed he had broken several ribs, with reports blaming the incident on snapped cables.

But following an investigation by the Actors' Equity Association, the real reason behind the accident was revealed to be an error on the stage crew's part. A statement from the organization reads, "Actors' Equity Association worked today with the Department of Labor, OSHA and the production to determine that the cause of the accident at last night's performance of Spiderman (sic) was, in fact, human error."

Tierney is the latest person to be injured during the run - actress Natalie Mendoza suffered concussion on the first night of previews when a rope broke and hit her on the head, and another "Spider-Man" stuntman, Kevin Aubin, broke both wrists during rehearsals in October.
