World War Z wastes no time. Within minutes, a normal morning in Philadelphia turns into total panic, and the film hardly stops to breathe for the next hour. This is its best idea. The zombies do not shuffle. They sprint, swarm, and spread faster than anyone can understand.
Brad Pitt is the anchor. Gerry is not an action hero who solves everything with a gun. He watches, thinks, and notices what others miss, and Pitt makes that calm feel believable. Daniella Kertesz is a standout as Segen, an Israeli soldier who says little but makes a strong impression. Mireille Enos does her best with a smaller role as Gerry's wife, Karin.
The big scenes are what people remember, and the attack on Jerusalem is a true spectacle. The computer-made swarms have aged, and they can look more like a wave than a crowd of bodies, but the scale is still impressive. Marco Beltrami's score and the use of Muse's music add to the rush. The film is PG-13 and has very little blood, so it builds its fear with speed, sound, and numbers.
The surprise is the final act. After all that size, the film gets smaller and quieter, moving into the hallways of a research lab. Some viewers love this slow, tense change of pace, while others feel it falls flat after what came before. The story also gives us very little of the world beyond Gerry, and the family characters stay thin. It is not the deep political story the book told, but it is a smart and exciting thrill ride.
