We took a trip through decades of the genre and came up with a list of the most important and best hard science fiction movies of all time. They are the essence and the foundations of the book of sci-fi rules that’s still being written as we, the audience, become much more self-aware of our relationship with technology, the future, and whatever those two will bring.
Your list is far better.
I loved Niven’s books, one of my favorite sci-fi authors. However, he might be a hot potato for studios, he had some proclivities that are indefensible.
Plus, I don’t know how you’re gonna make films about Luis Wu fucking his way around the Ringworld with various aliens. Really gonna have to sanitize the story a bit, or all of Niven’s aliens are going to have to be transformed to Star Trek aliens, basically humans with some weird shit on their nose and forehead.
