As early as 2011,
Hero Ventures approached
Marvel Entertainment about a traveling attraction. They agreed upon a seven-figure upfront licensing fee with a media royalty of 15% median royalty. Hero Venture then sought out additional funding for the project. On August 22, 2013,
Marvel Entertainment announced that it was working with
Hero Ventures on The Marvel Experience, a traveling production and attraction. On January 9, 2014, Hero Ventures unveiled the dome design image. Due to its popularity, Hero Ventures announced an extension of the
San Diego stay until March 1, 2015, and a shift in plans to visit
Philadelphia before heading to
Chicago,
New York, and
St. Louis for the show's opening in April 2015. Instead, the show was reworked. The tour went to Philadelphia, with plans to visit Chicago, New York, and St. Louis. In July, Hero Ventures announced that the show's summer tour would end prematurely, after only a three-week run in Philadelphia, for reasons not disclosed. Prepaid ticket holders were given refunds. ==Design==
