Besides having the cast with the most ever double letters in their names, Zodiac has much to recomend it. Downey is top notch, Gyllenhaal remains solid and Ruffalo has a long future ahead of him playing tough cops with a heart of gold. Anthony Edwards(GOOSE!!!) is excellent in a supporting role. All and All much better than similar films(Summer of Sam)in the past and a very watchable two and one half hours.
