Four versions of the superhero were depicted from the four eras of comic book history: Golden, Silver, Bronze and Modern. In addition, it included four versions of the Bat-Signal. Several Six Flags theme parks, formerly owned by Warner Bros., opened live-action "Batman Stunt Shows" as the movies increased in popularity. The now closed Six Flags Astroworld in Houston, Texas was home to a standing roller coaster known as Batman: The Escape. Six Flags Over Texas in Arlington, Texas is home to two roller coasters called Mr. Freeze, and . Six Flags México in Mexico City, Mexico has also a looping, suspended roller coaster named Batman: The Ride (Six Flags St. Louis has the same ride, as does Six Flags Great America in Gurnee, Illinois) as well as twin roller coasters named Batman and Robin: The Chiller. On the latter attraction, riders may ride on either the Batman or Robin versions of the coaster. But unfortunately in the 2007 off-season, the ride was removed after a long history of technical difficulties and occasionally breaking down. Six Flags Over Georgia contains a Gotham City area that contains the same Batman: The Ride and also features a looping coaster called The Mindbender that was adapted to fit the color tone of the Riddler after "Batman Forever" came out to fit the Gotham City section of the park it shares with Batman: The Ride. Six Flags Magic Mountain in Valencia, California has two Batman-themed coasters, the suspended coaster Batman: The Ride, and The Riddler's Revenge, a stand-up type roller coaster. This Six Flags park also features an entire themed area called "Gotham City" complete with architecture to match that of the fictional Gotham City. Warner Bros. Movie World in the Gold Coast, Australia, also has two Batman-themed rides. Batman Adventure – The Ride, revamped in 2001, is a motion simulator style simulator ride while Batwing Spaceshot is a vertical free-fall ride. In 2008, The Dark Knight Coaster opened in Six Flags Great Adventure and Six Flags Great America. Based on "The Dark Knight" film, they are Wild Mouse roller coasters, indoors, heavily themed, and give riders a feeling that they are being stalked by the Joker. Six Flags New England was originally going to receive this roller coaster; however, due to problems with building permits, the park scratched the project and then sent the coaster to Six Flags México.
