When ex-lovers Rick (Humphrey Bogart) and Ilsa (Ingrid Bergman) are reunited, they have one big obstacle that keeps them from running away together: her husband.
Ilsa: "I can't fight it anymore. I ran away from you once. I can't do it again. Oh, I don't know what's right any longer. You have to think for both of us. For all of us."
Rick: "All right, I will. Here's looking at you, kid."
Ilsa: "I wish I didn't love you so much."
