Spider-Man: Turn Off the Dark is still slated for a March opening on Broadway, a spokesman said on Wednesday, despite a storm of rumours about a potential overhaul and another opening delay for the beleaguered musical.

The $65-million US musical starring the comic book web-slinger continues to work towards an official opening night of March 15, Jaron Caldwell, a spokesman for Spider-Man's producers, told CBC News.

However, he declined to comment on film and stage director Julie Taymor's status with the show, which features music by U2's Bono and The Edge.

Rumours swirled about Taymor's future with Spider-Man as well as a possible overhaul of the troubled production this week, after reports in the New York Times and other outlets about the latest strife behind the scenes.

Citing anonymous sources, the media reports said Taymor may be leaving the production after struggling to improve the stunt-laden musical, which began previews in fall 2010 and has been plagued by technical problems and cast injuries. Taymor has not commented.

After five previous opening night delays, many theatre critics chose to buck convention and print their reviews of the show in February — before the official opening.

Producers blasted the critics — some of whom published scathing reviews — but those media outlets defended their decision. With the high price being charged for tickets, Spider-Man previews regularly sold out and the flood of amateur reviews already posted online, the critics said they were simply performing their professional duty of informing the public.

Spider-Man now holds the record for Broadway's longest preview period. It is also Broadway's most expensive show to date.
