Can never understand why men like these films. Some of these films only have like a 30% likeness to the actress, and with out the actresses voices it's just simple normal porn.
Right now it is unimpressive, but it's only going to get better. I saw a clip somewhere where they had replaced the actors, image and voice, in a short clip of Back to the Future. Wish I could remember where I saw it, I'd leave a link.
Eventually when there's enough processing power, you'll be able to scan a book, tell your app to make it into a movie, pick the cast, pick the director/sfx/soundtrack style. Probably a decade or 2 away from that, but it's coming. I can already sense that some internet troll is gonna re-release Basic Instinct with Sharon Stone being replaced by Danny Devito.
