Spoken by Humphrey Bogart (as Rick Blaine) in Casablanca...
Rick: I'm saying it because it's true. Inside of us, we both know you belong with Victor. You're part of his work, the thing that keeps him going. If that plane leaves the ground and you're not with him, you'll regret it. Maybe not today. Maybe not tomorrow, but soon and for the rest of your life.
Only saw this film for the first time about two years ago, and I thought it was brilliant. I could watch it everyday.
(Should mention that I am not your usual run of the mill lovey dovey weepie film types).
