I’ve seen car jumping scenes in which the chassis was clearly undrivably bent at landing. In fact they’d cut away fast from the landing because it was so obvious and the car had 2 more minutes of chase scene to run. (There has got to be a hell of a lot of crippled stunt drivers out there).
I have heard that there were 40 or so cars on the Dukes of Hazard set. Most were being repaired for the next jump.
"Hold on...I can feel the Percodan kicking in."
I know a guy who works for car commercial filming company. He told me they once had to film a car jumping something. The stunt driver crashed the car in practice, so they went and rented one for the ad.
