I read somewhere that Alec aimed the gun at her because he was filming a scene where the gun is supposed to be pointed at the camera, as if the viewer is supposed to be the one who sees the gun being pointed at them. Sucks majorly that she got killed by a gun that was supposed to be a blank gun.I remember hearing that an actor died a similar way. That Actor from an 80's show, was told the gun had blanks, not actual bullets, so he jokingly shot himself in the head fully thinking he wouldn't be harmed at all and ended up accidentally killing himself. The Show he was the star of got cancelled after his sudden and accidental death. CGI Guns would have prevented both tragedies.
