I checked my copy of "Car Life" from August, '69, which has a lengthy
article on the filming of the chase scene ("Filming the Frisco Flyers"). The Charger had whitewalls and full wheel covers, lots of those. I always wondered whose job it was to put new ones on the car after it tossed them off going around corners. I always look for the shot where the Charger takes out the camera in a blinding flash, which they left in the film.Three different drivers piloted the Mustang, and stuntman Bud Ekins, pal of McQueen and long-time stunt driver, did most of the driving. He also did the famous motorcycle jump over barbed wire as McQueen in "The Great Escape."The driver of the Charger was another long-time stunt driver named Bill Hickman, who really manhandled that beast. During one scene, the brake pedal went to the floor and Hickman threw the car into a broad slide, narrowly missing cameramen and SF policemen there for traffic control. None of the cameramen even moved. Real pros, all.
