All I remember:
Old astronaut man is lowered down a hole in an alien planet, and out from the walls of the hole, worms resembling vacuum-accessory heads latch onto his body, even on his head, and suck his blood out, I guess.
Also, there is another part where another male astronaut is fighting an invisible alien, maybe lizard-like, but big, and the guy loses as the alien rips his stomach open, I think.
Anyway, basically all the crew members die from an assortment of alien creatures on an unfriendly planet, or maybe it was a space-ship, or both?
Any help would be appreciated. Scary movie from my youth.
I believe that this is "Galaxy of Terror." Do you remember a woman being attacked by a huge worm, and another man who is killed by his own crystal throwing star thing?
It's definitely Galaxy of Terror.
