I saw this movie on TV (it could have been a TV show) probably around 1978, after school one day. It was in black and white, and basically it had a head that either communicated or controlled a spaceship only by looking from side to side with its eyes. The actor’s body was hidden so that only the head showed, and it seems like there was a lot of makeup on their face. The head might have been under glass, and there may have been a man talking to it. This was really schlocky sci fi stuff. I remember laughing about it with a friend back then. I know it’s a long shot, but I’ve put keywords into Google every way I can and cannot find an image.
It’s not b&w and may be too obvious, but I would swear from that description you’re talking about Zardoz.
Or maybe:

Way to go, Mr. Unknown!!! It was definitely Invaders from Mars. Maybe I saw it on a black and white TV back then. Thanks to you both!
Good job Mr. Unknown! Hope you will register for an account so I can keep track of your Solves. I believe you have two or three correct already.
