I have an enormous ladyhardon for Polish Posters and anything Saul Bass. Out of all of his posters I like Vertigo the best but my heart is spoken for by his opening titles for Golden Arm. I could sperg about him forever so I'll just stop now.
And also Metropolis which I was incredibly lucky to see the last restoration (95% complete as of 200 of in a local theatre.
I like the second one not only for its minimalism but because it's fun to imagine how many dumbasses got tricked into seeing a disturbing art film because "i wanna see Scarlett Johansson's titties hurr hurr!"
