Off the top of my head: Head. Three Colors Red and Blue – but not White, which I remember watching and finding painfully, cringe-inducingly unfunny. If… and O, Lucky Man, which were movies that just blew my mind when I was in art school, which I realize as I type is a terrible sentence to write. Oh! Stanley Donen’s Charade, which remains the greatest example of a Hitchcock film for me, despite not being a Hitchcock movie at all.
As you can see, I’m appallingly movie illiterate.
