True. I think it was Bruce Lee's son who did that.
Also, Jon - Erik Hexum. He was one of the stars of “Voyagers!”, a late-80’s TV show. Was goofing around with a blank - loaded firearm and killed himself by accident.
No, Brandon Lee was killed when a squib got stuck in the prop gun, but he was not playing with it and killed himself. He was shot during the course of filming “The Crow”.
