Actors expiring in order (spoiler)
Myself, and I'm sure many others, have noticed that the actors John Hurt, Harry Dean Stanton and, now, Ian Holm have died in the same order that their characters died in, at least as shown in the Director's Cut.
Okay, Ash "died" as a robot and Bolaji Badejo, who played the alien, died in 1992, but it is striking.
