What are some older movies that hold up extremely well?

I’m a huge fan of movies from every era (especially the 20’s, 30’s, 40’s, and 50’s) but some definitely have to be watched keeping in mind that some aspects might be dated. However in the past couple of months I’ve seen a few that hold up particularly well:

The Lodger (1927)
The Passion of Joan of Arc (1928)
All Quiet On the Western Front (1930)
M (1931)
The Old Dark House (1932)
The Thin Man (1934)
Sabotage (1936)
Rebecca (1940)
Diabolique (1955)
The Innocents (1961)

Are there any other movies you can think of that were ahead of their time?
