Casablanca or Citizen Kane?

Casablanca.

Both are good, but I'd go with Casablanca. It's so iconic that people quote it all the time without realizing that's what they're quoting. "Of all the gin joints....", "Here's looking at you, kid", "Play it again, Sam", "Round up the usual suspects" etc, etc...

Casablanca.

The rise and fall of CF Kane is compelling, but I prefer the war-romance hybrid drama contained within Casablanca. As a bonus, I think it's more quotable, despite the oft-referenced "Rosebud".

Casablanca. Kane has merit but its's not a film I'd want to rewatch.

Both are great but I choose Casablanca
