John Travolta is great in one of his best and most gritty roles as a soundman who observes an assassination while recording sound for a B-movie late at night. He gets caught up in the cover up and gets the help of the survivor, Nancy Allen, to assist him in getting to the bottom of this. Brian De Palma goes wild in the finale involving a huge Fourth of July parade with car crashes, thousands of extras, and fireworks. Beautiful Pino Donnaggio score as well.
