Kubrick is overrated to me as a director, writer, producer.
However, he is genuinely good as a photographer.
2001 was filmed in 70mm film, one of the few that were ever done in that time.
Do you want to guess when that film was made?
No, it wasn't early 1980s or late 1970s as most people assume.
It's fucking 1968.
That's the magic of 70mm and good photography, in an age of shitty blurry 35mm.
