Did you know that Vic Morrow and two child actors, Renee Shinn Chen and Myca Dinh Le, were killed in an accident involving a helicopter during filming on the California set of Twilight Zone: The Movie. Morrow, age 53, and the children, ages 6 and 7, were shooting a Vietnam War battle scene in which they were supposed to be running from a pursuing helicopter.
