  29 Imperials share role of Black Beauty
  John Pearley Huffman, New York Times
  To film scenes of the car used by the Green Hornet for a forthcoming movie, the car coordinator had to provide the production with 29 1964-66 Chrysler Imperials. Some of the cars had to be modified with roll cages, several were cut in half, and another had to be made strong enough to survive jumps. Here's a rundown on how the 29 cars were used for "The Green Hornet":
  One car was kept in pristine stock condition before it was modified into Black Beauty. On another, a chassis was modified with a Chevrolet V-8 and other items to show the car under construction. Two cars appear as stock Imperials before the transformation into Black Beauty, but include roll cages and Chevrolet big block V-8s for stunts. One Black Beauty body was used to depict the car under construction.
  One Black Beauty shows the car in its perfect state.
  Some of the cars had to be strengthened for jumps and crashes. To test how much punishment the Imperial could take, one was dropped about 15 feet from a crane. "We ran out of crane before we ran out of car," Dennis McCarthy, the coordinator, said about the Imperial, which is renowned for its toughness. One Black Beauty was equipped with a smaller Chevrolet V-8, roll cage and modified suspension to perform the jumps, which included a scene of the car flying through a window. Another car was needed to complete that scene, which shows Black Beauty buried nose first in the ground like a lawn dart. One Black Beauty was also built with a reinforced side so it could be hit by a truck.
  One car had a driving pod mounted on its roof so a stunt driver could pilot during filming inside the car with the camera looking out.
  Two cars show different levels of bullet damage.
  One Black Beauty was built to be chopped in half onscreen; one had the front drive power train from an old Cadillac Eldorado so it could be driven after being cut in half; and another was a half car for a scene in which it was buried.
  One non-running Black Beauty was built to show off its exotic weapons.
  Four Black Beauties were built as non-running "process" cars - parts and pieces that could be assembled or disassembled for shooting against a green screen with backgrounds digitally added later.
  Seven Black Beauties were modified for stunt work with large Chevrolet V-8s, racing brakes and roll cages.
