I’m trying to remember a dark comedy film I saw on late-night local TV in the early 80s. I seem to recall that it was a color, English-language movie, probably made between mid-60s and no later than early 70s. The opening credits showed images of big mainframe computers and possibly computer punchcards, so possibly the main character (a man) is a programmer or something related. I believe he commits a murder — can’t remember if it was his boss, a co-worker, or his wife. In the end he dies — maybe caught and executed? — and reaches the afterlife. He’s told that he’ll be reincarnated, but that his next life will be completely insignificant.
That’s all I can remember. Sorry to be so vague, but this has just recently popped back into my memory and it is driving me crazy!
