A rather ghoulish list, from Screen Junkies, concerning five movies in which cast or crew died while the project was being made:
I was aware of most of the mentioned works, particularly those whose lead actors died while making the film, Brandon Lee in The Crow and Vic Morrow in The Twilight Zone: The Movie. Both deaths, indeed all the deaths mentioned here were tragedies yet it is interesting to note the hows and whys of each of them, some more grisly than the others.
If there is one positive aspect to all this is the fact that the most “recent” of the listed tragedies occurred back in 1994, nearly twenty years ago. One hopes that those who work on film/TV projects have opted for better security.
