James Spader is a St. Louis yuppie who falls in love with Susan Sarandon, a 43-year-old waitress in the titular burger joint. They have steamy sex, have many fights about their class differences, and wind up together forever. White Palace isn’t much of a movie, but Spader comes through with another of his intelligent, understated performances, and Sarandon, as always, is superb — she invests each line with bottomless sadness and bitterness. See it for them, and also for Eileen Brennan as Sarandon’s fortune-teller sister and Kathy Bates in a brief bit as Spader’s co-worker. There is one classic exchange, when Sarandon accompanies Spader to his family’s Thanksgiving dinner and encounters a snooty designer who wants to know how she won Spader’s heart. “I dunno,” Sarandon says, “I guess I just give good blowjobs.” “I bet you do,” sneers the designer. “I bet you don’t,” says Sarandon.
