This is one of the most famous movies from one of the most famous directors of all time. It holds up well over time despite its very dated aesthetic because of the irresistibly engaging performances from the main cast. It amounts to a surprisingly leisurely ride through the espionage and mystery, and the famous Mount Rushmore chase is solid, albeit abrupt. The dialogue is gorgeous and refreshing, especially these days when writing in films is often so sloppy. The plot is interesting enough to keep the audience’s attention without attempting to pose a big enough distraction to detract from the character moments which really comprise the heart of the film.

Closest comparison: It’s the Alfred Hitchcock movie that isn’t Psycho.
