I love title sequences so much but my top favorites are West Side Story and It's A Mad, Mad, Mad, Mad World (both by Saul Bass!) https://twitter.com/TyleKurner/status/1260263597021642752

Also there seems to be a lot of people replying to this thread who don't know what a title sequence is. I guess that makes sense since they've (unfortunately) fallen out of style for most films.

Marvel movies stand out as an exception to this rule, and it's one of my favorite things about them.
