The Godfather is also a beautiful movie to look at. As is Casablanca. The art direction put to film is outstanding, and can probably never be equalled. That's why films like these are studied for years and years at the best film & theatre schools, or are hailed by movie journalists worldwide.
The sequence where Michael Corleone visits his father, Vito, in the hospital after he's been shot, and then needs to move him and await the killers to arrive, could quite possibly be the greatest 10 minutes put to film ever. It's as close to perfect as you can get, with the directing, sound editing, screenplay, and of course, the 'oak' colour lighting coming together in perfection just for that one entire sequence.
