“The Marvel Experience”, a traveling, interactive indoor theme park intended to bring the Marvel universe to cities across the country will instead be shutting down early. The show’s summer tour will end after it completes a three week run in Philadelphia, producers have confirmed.

Debuting earlier this year with appearances in Phoenix, Dallas and San Diego, the show was retooled before the current run, which was also meant to include stops in Chicago, New York and St. Louis, following Philadelphia. No reason for the cancellation was given, but refunds will be provided.

The $30 million dollar production was jointly produced by L.A.-based Hero Ventures, Marvel Entertainment, and Michael Cohl and Jeremiah J. Harris. This isn’t Cohl and Harris’ first Marvel headache; the duo also produced Spider-Man: Turn Off The Dark, the notoriously troubled musical that currently holds the title for most expensive Broadway production.
