Well, if the people in charge of shooting are too incompetent to make sure they are using blanks instead of actual bullets (or if the actors are stupid enough to forget that even blanks are dangerous if used carelessly) he has reason to be scared. However, that doesn't seem to be what he's getting at.
(That said, I think that California's gun laws -- basically, you can't have one unless you can prove that you need it -- should be applied to Hollywood. Obviously, Hollywood doesn't need real working guns any more than they need real working phasers. Of course, then they'd have to spend more money on SFX, which is an intolerable imposition since it would affect the Elite[tm] rather than ordinary working stiffs.)
...or if the actors are stupid enough to forget that even blanks are dangerous if used carelessly.
True . There's that actor(Eric Hex.. something) who put a pistol, to his head as a prank, thinking it was harmless because it had blanks in it and pulled the trigger...
He laid comatose for some time until he died.
He chose...badly.
The actor was John-Erik Hexum.
Had to google it .
