Seven Eleanor replicas were made for use in this movie. Five of them were totaled during stunt sequences. Nicolas Cage and Jerry Bruckheimer kept the remaining two. Cage regularly takes his out for joy rides, while Bruckheimer is afraid of driving his.
Nicolas Cage did most of his own stunt driving for the film. He attended the Bondurant Driving School in Phoenix, Arizona, Willow Springs (another car driving school), and the Bobby Ore Stunt Driving School in preparation for the film. He liked the race car driving school so much that he continued to pursue it as a hobby after shooting was completed.
When Mirror Man (T.J. Cross) is talking to the clerk at the police impound yard, a sign can be seen in the background that reads "If you leave your car unlocked, it will be gone in 60 seconds." This same sign was used in La grande casse (1974).
When The Sphinx (Vinnie Jones) and Mirror Man (T.J. Cross) are stealing the Hummer pickup truck, it was not originally scripted for the police car to fall off of the ramp. Vinnie Jones had pushed the stunt driver just a little off of the ramp, but did not have enough room to drive the Hummer past. He gave it a little more gas, and the Hummer smashed the car off the ramp. In the elevator afterwards, Jones said to the stuntman, "That'll teach ya!"
Christopher Eccleston spoke with his natural Lancashire accent in the film because he noted that in American films, the English accents are always either posh or Cockney.
