Rumors are circulating that Spider-Man: Turn Off the Dark has run into a financial snag that could threaten the production schedule of the big-budget Broadway musical.

Variety reports that preparation work for the show stopped this week, apparently due to "cash-flow obstacles" that producers -- Marvel Entertainment and Sony Pictures, among them -- are moving to resolve.

A spokesperson told the trade paper that production remains on track for the show to begin previews on Feb. 25 and open sometime in March.

The musical, directed by Julie Taymor (The Lion King) and featuring music and lyrics by Bono and The Edge, so far stars Evan Rachel Wood as Mary Jane Watson and Alan Cumming as Green Goblin.

Although the role of Peter Parker has yet to be cast, we already know that once he dons the Spider-Man costume, he won't sing.
