* Chrysler loaned five Challengers to the production company, but demanded that they be returned after filming [[HonestJohnsDealership so they could be sold to unsuspecting customers]]. This is why a 1967 Camaro is destroyed in the climax ([[EveryCarIsAPinto and was filled with dynamite to explode on impact]]). According to stunt coordinator Carey Loftin, they had to use parts from one to fix another, because they "really ruined a couple of those cars." Makes one feel sorry for the buyers of those five Challengers.
* {{Irony}}: Gilda Texter, the naked woman on the motorcycle, went on to a career in Hollywood as a costume designer.
