Help me remember two films from my youth

^ I know the first one, saw it when I was a kid. I always thought it's Russian film (sounds like a lot of "eastern" sci-fi authors like Stanislaw Lem or brothers Strugacki). That's psycho.

But Alien 3 ? Heh, you got me there, because there are many clues it can be it - deserted base (prison), bunch of losers (prisoners), one of them is "it" (Ripley), epic final fight.

BUT I don't think that's it. I remember that the hero was a man and he was released from prison and went with team of other people TO that planet/moon.

Yeah, you get the first one right, now it's time to see how psycho it actually is, after all this time.

Anyway, certainly not serenity. You know, S. is a very favourite movie of mine (serving as "conclusion of prematurely abrupt tv series) and there are differences.

Stick to points, even though I don't remember the name, I still have movie in my vivid memory. 

There is group of probably prisoners (7-10 people) who are sent to deserted base on some moon or planet (doesn't matter). It soon turns to survival horror, where one of them kills others and nobody knows who it is. I think it ends up with just two people (hero and monster) being alive, confronting it in big fight. I think.
