Forgot to mention that for me the most influential of all movies on the list was The Budapest Hotel.
Why? This led me to start reading the works of Stefan Zweig, who is starting to be rediscovered after all these years. I'm currently reading his memoirs, The World of a Yesterday.
As his works in paperback have been re-published by The New York Review of Books Classics, this led me to explore their catalogue -- which is tremendous -- and I have recently read such books as Kingsley Amis' Lucky Jim, not to mention a couple of WW I related titles. I will soon be starting a book by Pushkin they republished, The Captain's Daughter.
