When filming the yacht scenes with Vince Vaughn, Todd Phillips became very seasick and mentioned that he hated boats. When asked why he included one in his screenplay, he vowed never to write or shoot a scene on boats again.
About ten 1975 to 1976 Ford Gran Torinos were totalled during production. Only two Torinos from the film were intact. One of them is a 1976 Gran Torino with the Starsky and Hutch (1975) paint job, and the other was a base 1974 Torino, which had been in storage. In reality, the 1976 and 1974 Torino, which were used in the film, were repainted with the white stripe resembling the one used on the television show. All of the movie Torinos used fifteen-inch slot mag rims. They're not available new, so the rims (originally known as the Ansen Sprint, first introduced in 1963, and subsequently copied by several aftermarket wheel manufacturers, E-T Wheels, Appliance, Cragar, Fenton, American Racing, U.S. Wheel until the early 1980s) mostly came from swap meets, salvage yards, or eBay.
