The 1968 Ford Mustang GT featured in the Steve McQueen thriller "Bullitt" will be sold off, auction company Mecum announced Wednesday. McQueen (and his stunt double) tore through the streets of San Francisco in the green Mustang to create the 1968 film's most iconic segment. For decades after the movie's release, though, the "Bullitt" Mustang disappeared. (Another version of the car, the "stunt double" used for some of the action shots, was also lost for years but resurfaced in Mexico in 2017.) "I can promise that we have thought this through together and decided that this is the best decision for the family," Kiernan wrote.
