Mr. Freeze is a steel roller coaster located at Six Flags Over Texas in Arlington, Texas. This LIM-launched roller coaster is essentially a mirror image of the ride of the same name at Six Flags St. Louis. When it first opened, this coaster had over-the-shoulder restraints (commonly called OTSRs), which were replaced with individual ratcheting lap bars for the 2002 season. Mr. Freeze was supposed to open in 1997 with the release of Batman & Robin (which was the main reason Gotham City Area was made). Arnold Schwarzenegger and George Clooney were scheduled to appear at the opening of Gotham City and be the first people to ride it, but troubles with the LIM system delayed the opening until 1998. This was the main reason why Schwarzenegger never appeared (since he had another promised project at the time; Clooney decided not to come because Schwarzenegger didn't).
