OK - Now I need some help. Here's a super vague description of pretty much the only seen I remember (This has to be an 80's movie) :
I believe it takes place in space (might not though) or a planet other than Earth. There is a main villain who I think feeds off of women. I think he
has some sort of tentacle thing that wraps around the woman's body or neck and he sucks the life out of her.
The scene I remember shows a couple of henchmen presenting the woman to the head bad guy and either her neck is broken or she is unconscious but
either way the hench men are holding here in an upright position and her head is floppy...
OK I lied - there is one more that scared the living crap out of me when I was about 4 (1985ish era). There was a creature that goes into a couple or
a woman's house. It's pretty violent, and tackles the woman, then puts it's arm/ hand over her mouth and I'm pretty sure it sucks the life out of
Good luck! I'm still searching myself!
