The 13th Floor. An early Sci Fi film about AI before AI even became a popular concept. It's about creating AI that goes beyond anyone's current idea of AI. But it's dated, because the state of the art when the film was made was 64 bit microchips on what looked like Apple II computers, but it did have a warehouse full of refrigerator sized servers or "thingamobobs," which made it seem highly technological. I always get a kick out of that in older Sci Fi films that create magificence out of Commadore computers.
But the premise was possibly the first of it's kind, the first I was aware of anyway, and a premise which sparked similar plots afterwards. It would be on my highly recommended list for Sci Fi fans.
