It is the most atmospheric movie I've seen in a long time. I really liked it, are there some other similar movies you guys could recommend?
The type of film you seem to be describing is a
Hard Science Fiction film
set in outer space. Other than the preceding suggestions from Wikipedia, I would just say the usual suspects 2001, Sunshine, Solaris, Alien, and not much else. It's kind of a niche subgenre. Most sci-fi tends to be action, horror, or silly in either its tone or its tenacity towards realism.
On the other hand, maybe you were referring to a hard science fiction film that is also a suspense (aka thriller) film (not necessarily set in outer space). Or maybe you thinking mainly of it's isolation based story. There are probably a few more of those kinds of films and some of them might be good. I guess you'll just have to sift through all the crap that is imdb searches, wikipedia lists, amazon recommendations, and google searches through random blogs.
Regarding Moon, it is funny how with all of the film's realism they didn't even bother with the fact that gravity on the moon's surface is only 1/6th of the gravity on the the Earth's surface. The director joked about the discrepancy in the special features, but it was probably more of a function of the films budget ($5 million). Other films try to deal with low or no-gravity effects by using wires, actually filming select scenes in
Vomit Comets, or using a sci-fi technological convenience Velcro socks, magnetic boots, centrifugal motion, or (the most common, but ridiculous) artificial gravitational fields.
I'm sure it would be prohibitively expensive although nonetheless cool, if a movie studio would build a small sound stage that is in fact a large
controlled free-fall elevator. Sure it would only provide a few seconds of no or low gravity, but that would be all you would need for a couple of shots that would greatly enhance the realism of a sci-fi film.
