(CONFLICT OF INTEREST) If you gave Flannery O'Connor a Cinemascope camera, a moratorium on God, and free rein of Seattle, the resulting movie would be not unlike Police Beat. The city in Police Beat is wetter, riper, and brighter than the Seattle you know. There's a moment when the hero, a bike cop, smiles, and the music quickens, and everyone in the audience is lifted out of their seats. I defy you not to love this movie, and I'm not just saying that because Charles Mudede is sitting next to me. (Varsity, 4329 University Way NE, 781-5755. See Movie Times, p. 87, for details.)
