Or... Unidentified Flying Oddball. Same film, different titles. It's based on Mark Twain's book; A Connecticut Yankee in King Arthur's Court or A Yankee in King Arthur's Court as it was originally known. Confusing or what! I've never read the book but I have seen the film, a very long time ago. I think it was entertaining enough for the time although it wasn't Star Wars so it probably had a lot to live up to and was never going to manage it. Interestingly, all these years later, I know which one I'd sit down to watch on a rainy Sunday afternoon.
