Well, some of the filmmakers I cover include Lang, Roy, Kurosawa, Deren, Pasolini, Bergman, Leger, Bunuel, Dulac , Beckett, Dali, Eisenstein, Brakhage, Coppola, Berkeley, Chabrol - everything from European modernism and surrealism to Hindi cinema, nouvelle vague, Soviet cinema, studio Hollywood, Japanese cinema and animation, Sixties and Seventies arthouse, Blaxploitation etc. etc.
I tend to teach films that hook in to other cultural phenomena of the time, like Surrealism, political civil rights movements or pop art, so you get a nice comparison across art, music, stage and film. It’s rare these days to teach a film-only course: most of mine are comparative, looking at film in context.
