Trashie's list of apocalyptic flix included killer computers, aliens, zombies, natural disaters, disease, nuclear war, and just about everything else you could think of. But he left out a couple of my favorites--unspeakable eldritch gods, jealous archangels, and wacko religious cults. So here's my list which does include many of his choices.
As good as Will Smith was in I AM LEGEND, you owe it to yourself to see this film which is the closest adaptation of Richard Matheson's novella.
See the full review, "IT MAY BE OLD BUT ITS STILL GOT BITE".
Once a war raged in heaven between the angels. Now there will be a second. Stay away from LEGION and see this instead. Christopher Walken stars as ArchAngel Gabriel, and Viggo Mortenson has a cameo as Satan that will chill you to the bone.
It's science fiction, but with more gore than most horror movies. And it's a little complicated too. An upper class of people in a post apocalyptic society spend their lives plugged into a computer where they sleep and dream their deepest fantasies. One young woman decides she wants to see what life is like on the outside, but except for Bruce Campbell, it ain't pretty.
Set in Hollywood of the 40 where "movie magic" is really magic, this is the story of Phil Lovecraft a hardboiled detective who finds himself up against some heavy duty evil that's trying to bring Yog Soggoth into our world. The perfect casting of Fred Ward as Phil Lovecraft makes this bit of comic horror noir a dream come true for me.
