I have a couple of movies I've been wondering about for awhile, so I figured I would take a shot at someone here knowing them.
The first one is a creature feature from the 80s. Two brothers are backpacking, and spend the night at a bed & breakfast. As I recall, one of them is dragged under his bed by the monster and gets killed. In his quest for revenge, the other one meets and falls in love with a beautiful woman (of course, that happens in many 80s horror movies).
I don't expect anyone to know the second one, because my memories of it are so vague. I'm fairly sure it was from the 60s, and was about an alien invasion. I have the impression the aliens could control a person's mind, and I don't recall it showing them very much, if at all. The only scene that stands out to me, because it was so horrifying to me in my extreme youth, is a woman going into the kitchen. After a couple of minutes, she picks up a knife to slit her wrists. I can't remember if she was successful, nor if she did it on her own or was being controlled.
Thanks in advance for any help anyone can give me.
The 1st sounds like "Mutant" (1983). The younger brother gets dragged under the bed.

For the second, I wonder if you could have seen "The Brain Eaters" (1958). The others that seem probable:
"The Crawling Eye"
"It Conquered the World"
"Zontar: The Thing from Venus"
I don't remember the threat of slit wrists in any of them, but the general plot fits.
