CASABLANCA is the USUAL movie I pick for these black and white film memes. (that, or THE MALTESE FALCON).
(both feature Peter Lorre, which is why I played him as a character in many @skiffyandfanty.bsky.social Torture Cinema skits way back when)
Lorre is great in Casablanca, but I love it for so many reasons, the biggest of which is that the decision Rick makes at the end of the movie is, to me, the definition of how to really love someone.
