The Mist link
Most people I talk to haven't seen it--it's a great film with small-time actors who are all amazing in potraying a small-time Maine town that goes completely crazy when the mist rolls in, and there are monsters in the mist. Specifically, a bad situation is made unbearable by a woman who believes that this must be the rapture--she begins citing scripture and starts having converts, the worse things get, and most of these things, she hasn't exactly helped. I don't want to spoil things but religion is a huge player in how a solitary bigot makes a place that is otherwise safe into somewhere dangerous. Directed by Frank Darabont who also did The Green Mile, Shawshank Redemption, and currently is doing The Walking Dead tv series on AMC.
The Man From Earth link
Pure, glorious science fiction: Suppose a man, manages to live forever, because his body is able to turn over cells perfectly and renew his body? He is mortal and would die just like you and me, except that his body doesn't run down or age beyond the mid-30's, where he is stuck forever. Religion is mentioned but there's so much glorious glorious material and dialogue that I don't want to ruin it.
It's on the top 50 on imdb's Science Fiction movies, but I've met precious few others who've watched it. It's one of my favorite movies and the characters are spot-on. If you're expecting special effects or anything crazy in this, though, you don't get them. It's just professors talking to a friend for the entire movie, but so well done, and well-written.
Both are on the "must-watch" list. I've noticed both of these are science fiction with a light touch...but they are very good. It's about the story, not the budget. *shrug*
