“Music Box” (1989) is a courtroom drama that keeps you guessing. I mean, guessing where the drama is. It’s a federal prosecution of 40-year-old war crimes that took place in Hungary. An open and shut case. The suspense comes in waiting to see if the defendant will admit his guilt to his defense attorney daughter (Jessica Lange). Your faith in the courtroom movie formula starts feeding on itself, however, and you begin rooting for a big payoff that proves Papa innocent. The twist? He is suddenly, definitively shown to be guilty. Interestingly, it makes for a sadder, but better, story.
