there has been rumors over the years that footage of the accident exists on the black market, but the producers say it was destroyed. i'm surprised you never heard about this, i've seen plenty of TV documentaries and other things where this has been mentioned. but it was in 82, so it's not like its recent news or anything lol. but the real tragic thing about it is that the 2 kids weren't even supposed to be on set at the time (child actors can only work 4 hours a day), and Landis had them come back after they had done their work for the day to film this stunt/scene
