The indoor high-tech traveling theme park "The Marvel Experience" has stumbled and will cut short its summer tour.

Producers of the show that includes 360-degree projections, holograms and a 4-D motion ride said Sunday its big debut in Philadelphia will be its one and only stop. The Chicago, New York and St. Louis legs have been cancelled.

Refunds will be available. No reason was given for the show's abrupt cancellation.

It's another black eye for co-producers Michael Cohl and Jeremiah J. Harris, whose "Spider-Man: Turn Off the Dark" was a costly failure on Broadway. Hero Ventures, a Los Angeles-based entertainment company, and Marvel Entertainment also produced the tour.

The $30 million show had previously made stops in Phoenix, Dallas and San Diego before being retooled for the current run.
