Would this film be considered so great if another director made it?
If it wasn't the famous Kubrick who made the movie in his early days, do you think it would get this amount of praise?
For example, "The Asphalt Jungle" is an incredible, great film (probably better than this and much more seminal) and it isn't even in the top 250 on imdb. It only has around a measly 7000 votes, while this has over 20,000 votes.
Weird, huh?
