A perpetual flow of 130 vehicles (including police cars, pedestrian cars, motorcycles, and large trucks) had to always be in working condition with multiple duplicates on standby. Some nights every Mustang was under repair.
Seven Shelby's were made for the film. Many were wrecked multiple times and parts of some would be added to others to create a new car. In all, 13 versions of the Shelby were wrecked in the making of this film.
To catch all the breakneck action from both inside and outside the Shelby Super Snake the director used a variety of cameras, numbering anywhere from 18 to 42, in any given scene. The cameras ranged in size and format, including state of the art digital RED Epics.
Picerni's team carried out over 20 air cannon launches. They also executed 25 pipe rims, which involves running the car up a pipe and turning it over. They did 40 turnovers, which is a huge amount for one film.
Steve Picerni drove the Shelby, going 70mph, with two police cars in pursuit and five stunt cars coming straight at him. The scene culminated with a "double cannon"-both police cars crash and catapult over the Shelby.
