How we cite our quotes: All quotations are from Casablanca.
Quote #1
SAM: Leave him alone, Miss Ilsa. You're bad luck to him.
While Casablanca is a love story, it's usually Rick and Ilsa that get all the attention in that department. But let's not overlook Sam's love for his friend either (a love that goes both ways, mind you). Here he is looking out for Rick, being a good wingman. He knows the emotional distress that's sure to come from another encounter between the two, and is doing his best to prevent it from happening. He probably knows it's hopeless, but at least he tries.
Quote #2
RICK: I remember every detail. The Germans wore gray, you wore blue.
What's a surer sign you've been harboring loving feelings for a person than that you remember every detail of your time with them? The clothes they had on, the way they were wearing their hair, their habit of talking with their mouth full… Rick's clearly a smitten kitten. You don't recall what just anyone was wearing on a random day years in the past.
Quote #3
RICK: Here's looking at you, kid.
This famous line is repeated several times in the film, and it's apparent that this is/was Rick's little term of endearment for Ilsa. It's a bit more of a mouthful than a simple "sweetie pie," but it has the advantage of sounding silky smooth in addition to being sweet. Which is totally Rick's M.O.
