Lesser-known science fiction movies
I love science fiction in all forms, and I can't resist watching almost any sci-fi movie. So, I watch a lot of them. It's a bit annoying how "sci-fi and fantasy" became the standard pairing. In my eyes, these genres are exactly opposite. It's like grouping movies about horses with movies about cars.
Anyway, here are some lesser-known science fiction movies that I recommend.
The Man From Earth
Can a bunch of people sitting in a room, talking, be great science fiction? Yes. (Pro top: do not watch the sequel.)
Primer
The hardest time-travel story you can find in movie format. Shane Carruth is doing something truly different. Fun easter egg of sorts: there's a time-travel episode of Tales From the Loop (a brilliant little sci-fi series, too), and Shane Carruth appears in a cameo role which fits him so much.
Pandorum
It starts in a pretty banal setting of "awaken in a spaceship, something happened, omg", but then goes into a very interesting direction. If Passengers is a cheap airport novel, then Pandorum is its serious counterpart.
Upstream Color
Another film by Shane Carruth. More approachable that Primer.
Coherence
Don't you love it when reality bends?
Timecrimes (Los cronocrímenes)
Who can resist a time-travel paradox? I guess there isn't anything ground-breaking, but damn it's a good film.
Prospect
One of those movies that doesn't bend your mind or change your world, but brings you to another universe for a couple of hours.
Vesper
I can pretty much copy the description from Prospect and paste here.
The Artifice Girl
Philosophical horror is probably the best way to describe this.
There are some good movies which come from big studios and are probably more known than the ones above:
Here are some movies and TV-shows which I like mostly due to nostalgia. They are kinda trashy.
