Directors Steven Spielberg and John Landis were charged with involuntary manslaughter for a death on set of the Twilight Zone movie due to a helicopter spinning out of control and killing three actors.
Adult male actor and two child Asian non-actors were to do a stunt in which they run across a river while huge pyrotechnics go off in the background and a helicopter flies overhead. Since they wanted to do this at night and wanted to avoid potential denial from the fire marshal some of the production team lied about the fact that there would be children involved in the stunt. The children shouldn't have been working that late and should not have been that close to pyrotechnics of that nature. They started filming.
The helicopter was jostled by the huge explosions which sent it spinning out of control. The helicopter landed in the worst possible way: blades-first onto the three actors. The helicopter's right skid slammed into one of the kids, killing her. Then its whirling main rotor ripped off the middle-aged actor's head and the head, a shoulder, and an arm of the other 7-year kid.
They immediately announced that all cast and crew needed to immediately go home.
There were a large number of lawsuits that followed, essentially charging them with negligence. They were acquitted of, I believe, all charges.
