<Tr> <Td_colspan="2"> Mr. Freeze: Reverse Blast at RCDB Pictures of Mr. Freeze: Reverse Blast at RCDB </Td> </Tr> <P> Mr. Freeze: Reverse Blast (previously known as Mr. Freeze) is a steel, launched, shuttle roller coaster located at Six Flags Over Texas in Arlington, Texas and Six Flags St. Louis in Eureka, Missouri . The two rides, mirror images of each other, are based on the famous Batman villain Mr. Freeze, and were originally based on the 1997 film Batman & Robin . Both versions use linear induction motor (LIM) launch systems to accelerate riders from 0--70 mph (0--113 km / h) in 3.8 seconds . </P> <P> Mr. Freeze was planned to open in 1997 with the release of Batman & Robin . Arnold Schwarzenegger and George Clooney were scheduled to appear at the opening of Gotham City at Six Flags Over Texas 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). The ride itself was fabricated by Intermountain Lift, Inc . </P> <P> When it first opened, Mr. Freeze used over-the - shoulder restraints (commonly called OTSRs), which were replaced with individual ratcheting lap bars for the 2002 season at both locations . </P>
