Ill-fated just doesn’t seem strong enough language to describe the series of troubles that have plagued the Broadway version of one of Marvel’s most successful franchises.

Spider-Man: Turn Off the Dark has been repeatedly delayed, run far over-budget and suffered a series of catastrophes that left some cast members injured. Now, the production has a new problem: Actress Natalie Mendoza has walked away.

Mendoza -- who played Arachne, an evil love interest to the spandex-clad hero -- recently suffered a concussion during last month’s preview performance, and now she says she will not stay with the production. “It has been a difficult decision to make, but I regret that I am unable to continue on Spider-Man as I recover from my injury,” she offered in a statement.

The musical, already delayed four times, is scheduled to open on February 7. Currently, those behind the production are saying that Mendoza's absence will not delay the show again. It is believed that one of her understudies will take on the role full-time.

Four other actors and stuntman Christopher W. Tierney have been injured on the set. Tierney suffered a 30-foot fall when a safety tether failed on December 20. He has undergone back surgery and is currently receiving treatment in a rehabilitation facility. Mendoza was injured by a rope that struck her head offstage.

Injuries among Broadway actors are not uncommon. Stage heavyweights who have suffered injury while working on productions include Nathan Lane (The Frogs) and Idina Menzel (Wicked).

So far, the cost of the production is a whopping $65 million -- which easily trumps Broadway’s next-costliest show (Shrek, $25 million). Spider-Man: Turn Off the Dark will open at the Foxwoods on Broadway ... or so one hopes.
