My favorite Stanley Kubrick film is 2001: A SPACE ODYSSEY. Not much on the acting, but the special effects were cutting edge. And the marriage of classical music was amazing. I was 14yrs old, a science fiction fan, and really into the US space program. It is a classic, the apes were kind of hokey, however🙂
Have you seen Killer’s Kiss? Very early Kubrick noir. It’s been on Turner Classic Movies a few times, very interesting if you like the genre.
