This is when an actor or actress appears in any number of movies, and there's a huge number in which their character doesn't live to see the end of the film. Of course, it doesn't have to be that; there can be a few Disney Deaths thrown in the mix, but the idea stands that these performers have a very unlucky habit of dying in loads and loads of movies. Almost inevitable if the actor is confined to villainous roles. See also Vasquez Always Dies, when actresses that play Action Girls meet this fate, and Black Dude Dies First, when it's a black actor that gets offed more often than he likes.
