50s/60s B Sci-fi Movie

I saw this on like the 4pm movie like they used to have every afternoon.  The story line is 2 astronauts return to earth from a space mission.  I believe there was a larger crew but they were all killed.  An alien somehow gets on the ship ( it’s very large so this is a conundrum in itself). The creature has telepathy/ mind control over humans.  The hero is immune because he has a metal plate in his head.  Toward the end of the movie, to prove his complete control over humans, the creature has the 2nd astronaut ( the one that was not immune but has been assisting the creature throughout the movie) walk into his mouth and eats him.  You can hear the crunching.  This also gives you a idea of the size of the creature, looked like a large rock with a mouth.  The other astronaut saves the day and prevents his pretty lady friend from becoming its next meal by killing it.  That’s the best I can remember.  It’s driving me crazy.  There are so many B movies form this era.  Please help.

    1. Thanks, but that’s not it. These are astronauts newly returned from space. Again, I believe all but 2 of the crew were dead. I think the metal plate thing is throwing everyone off. This alien is a real alien. It sort of looks like a giant chocolate macaroon. You only see the creature in the last 5 minutes of the show, typical of the genre.
