Evan Rachel Wood has dropped out of the Broadway tuner “Spider-Man, Turn Off the Dark,” which the rumor mill says is gearing up to begin its much-delayed preview period in late summer ahead of an official opening sometime around Halloween.Producers of “Spider-Man,” in which Wood would have played Mary Jane opposite Reeve Carney as Peter Parker and Alan Cumming as the Green Goblin, would not confirm new dates for the production, but did acknowledge that Wood has exited. “Evan Rachel Wood has departed ‘Spider-Man, Turn Off the Dark’ due to a scheduling conflict,” producers said in a statement. “Casting is underway to find a new Mary Jane to join the rest of the cast in the production.” The big-budget musical offering, with music by U2′s Bono and the Edge, was originally skedded to open this spring before that timeline was derailed by difficulties in securing the funds for the enormously expensive new tuner. Observers estimate the budget for the technologically ambitious show, helmed by Julie Taymor, has skyrocketed into the range of $50 million. Last year producers encountered difficulties nailing down all the necessary coin in time for the original start date. A new lead producer, music industry vet Michael Cohl, was brought aboard in the fall. Most recently, the team behind “Spider-Man” publicly vowed to have the show up and running sometime this calendar year.
