I remember seeing a film (or part of) a long time ago (probably about 1988) and I'm trying to identify it. As I recall it was black and white. The only bit of it I remember had two men working with some equipment, trying to get it to work. The equipment was for playing discs (something like CDs, but I think they were metal). When they got it working it projected the image and sound of a third man. I can't recall if the image was purely a recording, or if it could interact with the other men and respond to them. There might have been an element of time travel in the film as well, or I could be mixing it up with something else. The film was in English (not dubbed / subtitled).
Thinking a little more about it I think that the person on the recordings was the boss of the other two and was issuing them their orders.
I seem to recall that there were lots of discs (in a heap on the floor?) and that the one they needed had a scratch on it. I think the machine might have been outside - they might have been on another planet perhaps?
