Producers of U2's musical Spider-Man: Turn Off The Dark said today that the $70m show will officially open on June 14.
In order to put in major changes and allow more time for rehearsals, the show has cancelled three weeks of previews, beginning on April 19.
Performances will resume after May 11, the producers, Michael Cohl and Jeremiah Harris, said.
Previously announced opening nights were February 18, 2010; December 21, 2010; and January 11, February 7, and March 15 of this year.
The show has already been panned by many critics, and four actors have been injured since rehearsals began.
Bono and The Edge, who wrote the music, have promised to write new songs for the show.
Earlier this week, the producers replaced the show's director and co-author, Julie Taymor.
If the production adheres to this schedule, it will play six-and-a-half months of previews and open two days after the Tony Awards.
The new date threatens to overshadow Broadway's highest-profile awards, the symbolic end of the season.
By delaying its opening, Spider-Man has taken itself out of the running for this year's Tonys, which are expected to offer stiff competition from other new musicals set to open this spring, including The Book of Mormon, Catch Me If You Can and Sister Act.
Meanwhile, in the latest mishap to befall the show, the Green Goblin has been defeated again during a performance -- by his own flight system.
Spidey's nemesis hung over the stage for three minutes during last night's performance before stagehands lowered him down. It was the second time this week that a technological mishap has interrupted a scene with the Goblin.
