I enjoyed Poodle Springs. It's not the best Marlowe, but Caan conveys that wounded virtuous knight with an understated solidness. Plus, Stoppard has some good humorous lines to balance the ugliness of the story. This Marlowe is aging and feels a little like a dinosaur. But he's just married to a stunner. My favorite line is when he finishes questioning a prostitute at a by-the-hour motel, and another lady of night spots him. "Hey, Marlowe, didn't you just get married?" she asks.
SPOILER ALERT: There is something horrible that happens to a cat. So, this is not a movie for everyone. I had to leave during that scene.
