Here’s a story that says that Bergman and Bogart, who had such great screen chemistry in Casablanca, didn’t get along that well off screen.
Compare and contrast to B-Lo (or Bennifer or whatever cutesy name you want to use for the about-to-be-ex-couple) who supposedly had great off-screen chemistry, but who just made one of the biggest cinematic turkeys (in more ways than one) of all time.
If nothing else, it shows how good Bogart and Bergman were as actors.
