Hey,

Saw this dodgy B grade sci-fi/horror movie back in the early or mid 90s (although it may have been made in the late 80s). What I remember is they are in either in space, maybe on a space station or a spaceship. There are several people in spacesuits, and some sort of creature which (I think) can take over their bodies by using a tentacle or arm up their back or their head (not dark side of the moon).

One scene I remember has two people trapped on either side of soundproof glass, another is this person in a large conduit or vent, and is pulled down by the creatures tentacle, and lastly one person is taken over by the creature and taps the person standing infront on the shoulder...I think.

For some reason I really want to see this movie again but have no idea what it is called. I've been searching through every horror film per year I can find but no avail.

Any ideas? Thanks
