Here are some films I'll recommend, which I haven't seen mentioned yet:

Death In Venice, Anomalisa, I Wanna Hold Your Hand, The Illusionist (I'm talking about the animated film), The Florida Project, Babe: Pig in the City, Last Year at Marienbad, A Night in Casablanca, Room Service, A Room with a View, and John Huston's atmospheric The Night of the Iguana.
