Creature (1985)

Heavily influenced by the movie Alien, a space ship lands on Titan, are targeted by a hostile life form, meet a melty faced German who eats a big sandwich, and end up feeling really stupid when the tiny alien that attaches itself to the astronauts head can be ripped off and destroyed by being stepped on.  Boy do they feel stupid, especially the dead guys.

It's hard to tell the characters apart since they all wear the same type of space suits and have over sized helmets.  The Ripley character is supposed to be able to handle anything but she ends up getting felt up by Klaus Kinski, and then gets lost on the planets surface.  Really, she's not much help at all.

This is more of a slow moving, dialogue heavy movie typical of space movies in the 80s.   The alien life force takes over the bodies of its victims and there are a few bloody scenes of space carnage, but other than Kinski there's not much of interest here.
