This movie was originally not a big success. But from the beginning something like a cult movie. Stanley Kubrick drove a few people almost nuts when he realized this in his perfectionist way.
Clearly as many movies, this is a matter of personal likes. It is for sure one of my favourites.
What many people don’t know is that this is not a movie made from the book of Arthur C Clarke, but Clarke and Kubrick wrote the script together and the book was only published after the movie.
I found an interesting article on WIRED which analyses in quite some details bout technical details of the movie. About what turned into reality, what didn’t, what might have been visionary. Very interesting to read.
