The old guy still has the muscle. A dozen years after the last Die Hard, Bruce Willis has reached a stage of Zen machismo. In this take, his Detective John McClane is paired with a neurotic hacker (Justin Long from the Apple TV spots) to abort the plan of a terrorist computer genius (Timothy Olyphant) to shut down the U.S. Terrific stunts and car crashes abound, but Willis is the steady, weary, stalwart anchor. At 52, he's Hollywood's last action hero.
