They Died With Their Boots On (1941)
Three horseman perished during the cavalry charge, one of whom was extra Jack Budlong, whose horse tripped as he rode alongside Errol Flynn. As he fell forward, he had the foresight to toss his sword ahead of him. Unfortunately, it landed handle down and stuck in place. Sound familiar, Charge Of the Light Brigade Fans? Jack was impaled on his own sword, and died in a L.A. hospital a few hours later.

Twilight Zone: The Movie (1982)
During the filming of a segment directed by John Landis on July 23, 1982, actor Vic Morrow and child actors My-Ca Dinh Le (aged 7) and Renee Shin-Yi Chen (aged 6) died in an accident involving a helicopter hovering above them. Without warning, the copter spun out of control and crashed, decapitating Morrow and one of the children with its blades. The remaining child was crushed to death. Landis, Steven Spielberg, and several other crew members were brought up on manslaughter charges, and were clearly in violation of several child labour laws. Chen’s parents also brought them up on a $200m damage suit without realising that rich famous people have awesome lawyers. Despite a long court battle, everyone charged walked away scot-free.
