Most of these movies are called psychological movies, but searching under this category I have not found anything that comes close to what I am looking for, movies like memento, 12 monkeys and primer are characterized by something, a person who knows information (Be good or bad), and is in a situation isolated from the rest of the population, no one other than the protagonist or a very small group of people knows what is happening and what it implies, that is the type of movies I am looking for, movies with isolated stories, if you know of any movie that makes you feel that I don't know what it is with the 3 movies I mentioned, please leave me the name and synopsis. (I had forgotten to mention donnie darko)
It’s not feature length, but 12 Monkeys is based on a short film by Chris Marker called Le Jetée which I highly recommend, along with all of Marker’s work, really. Marker deals a lot in documentary with a surrealist touch, and thoughtful narration. He’s a good old leftist too.
All the movies you mentioned are not just psychological, but are messed up temporally, so you might appreciate a newer movie called Time Addicts. Watched a bit of it and it was funny, dark, and wild, as a time traveling movie about meth should be.
The Manchurian Candidate is great (both versions are really, though I prefer the one from ‘62) as it deals with a character piecing together an experimentation plot involving hypnotism and proto mk ultra mind control. If I think of more when I’m rested i’ll jump back and comment again.
