"I'm shocked - shocked - to find gambling going on here!" (Captain Renault, just before being paid his winnings at Rick's Cafe Americain.)

Actually, there's a very interesting and fun echo of Casablanca in the Albert Brooks/Julie Hagerty movie Lost in America (1985). Whether it was intentional or not, I don't know, but I'd like to think so! When Julie Hagerty loses the entire "nest egg" playing roulette at the Desert Inn, she's obsessively calling for "22, 22, come on 22."
