5. Aqua and Val - Heartbeeps (1981)
Please, please don't watch this movie! Unless you truly think you'll enjoy it, I implore you to heed my advice. Andy Kaufman and Bernadette Peters play Val and Aqua, a pair of household servant robots who fall in love and escape to start their own family. They fail, of course. There's a good reason why you probably forgot about these two.
