I have more than thirty pre-70's movie to get through, and I'm constantly adding more through netflix burns.

I'm mostly trying to catch up on some great directors that I'm not totally familiar with (Huston, Welles, Wilder, Hitchcock, etc.), and see absolute classics that I'm somewhat ashamed of avoiding for so long (Casa Blanca, Seven Samurai, All About Eve, etc).

Anyone please feel free to suggest pre-70's directors for my catch-up list.
