Movie: The Thomas Crown Affair (1968)
McQueen helped the producers of the film with the design of the Meyers Manx. The body was set on a VW chassis with a Corvette Corvair six-cylinder engine in the back. The dune buggy only weighed 1,000 lbs and boasted an insane 230 horses. That's a lot of power for just a rec vehicle. In the film Crown takes Dunaway's character, Vicki Anderson, for a wild ride on the sandy beaches of Massachusetts.
They rode the dunes with a reckless abandon, and if it looked like they were having a blast, they were. No stunt doubles were used during those scenes, and McQueen was able to drive the buggy however he wanted.
