dangerous, even a blank can be deadly. it happened on movie sets before. in 1984 an actor was joking around on the set of a film with a real prop gun that was filled with blanks. he shot himself in the head at close rang. the force of that blank fractured his skull and he died. there s also the potential to misload a gun. this happened on a movie set in 1993. the actor brandon lee, the son of the great bruce lee, was starring in a movie where his character was supposed to get shot in the stomach, but when another actor fired a real prop gun in his direction, the prop gun loaded with blanks, turns out the gun had been misloaded. it hadn t been checked properly when it was loaded with blanks. there was an actual bullet, a real bullet accidentally lodged in the chamber of that prop gun. when the gun went off, it did fire a blank but it also dislodged the real bullet which hit brandon lee in the abdomen and killed him.
