I remember an old black and white sci-fi movie about a spaceship that was found in a jungle cave. There was a force field around it and every time a person would touch the force field they would end up in the spacecraft. The only other thing I remember is the force field started to grow and it was fell to the hero's and heroine's to stop that from happening. I know at the time it scared the heck out of me and now I would like to know if anyone knows the name of the movie. I'd like to know if it's as campy as I remember it.
