Alien 1 and 2: great. Saw ALien 3 tonight again, it was on TV: so so, nothing special, like Alien 1 but not as good. Haven't seen Resurrection yet.
No sound in space, since there is no oxygen. It's a vacuum out there. Sound is transferred by waves, it's need particles in the air to transfer it. Since space is a vacuum, sound cannot move anywhere. Hence it is silent.
Also, there's no pressure there either. If you step out into space without a pressure suit, you'd explode. Our bodies provide pressure from withing to withstand the pressure from the outside in our atmosphere. So when you'd go out into space, the pressure from the inside is still there but there is nothing to stop it. You can see that happening in "Outland".
As for the stars, I think that depends on where you are. If you look at all the nasa stuff they shot in orbit, there are stars visible. There's a huge sun out there, reflecting it's light off planets and stars.
