I'd really like to re-watch this sci-fi flick: a young boy is presumed dead because he fell into a river/was in a car that drove off a pier in New York. He freezes but doesn't die, and spends +/- 2,000 years staring at a statue of a girl/angel which sank to the bottom of the river. I think he falls in love with the statue?
While he's down there the human race evolves into very refined, delicate creatures. Eventually they find him, rescue him, and even manage to bring his mother back to life for 24 hours so that he can spend that time with her. I think they make a lot of replicas of him, but I can't remember why.
I thought the movie was called "The Blue Angel", but that doesn't seem to be right. "My" movie has nothing to do with Marlene Dietrich!
