A few observations:
* No citizen kane, some other "classics" have also been omitted
* No French cinema
* No silent cinema
* The omission of what is generally heralded as Kubrick's strongest work surprises me
* No Tarantino
The following films are on Lee's list and are French:
Les 400 coups (400 Blows), Truffaut
La Nuit américaine (Day for Night), Truffaut
A bout du souffle (Breathless), Godard
Paris brûle-t-il? (Is Paris Burning?), Clément
If you start like that, then there's no Chinese cinema either (and there would be certainly a few worth mentioning). I'd take such a list as being mainly made of Hollywood movies, as well as whatever is appealing to Hollywood directors.
