Los Angeles is destroyed by earthquakes, so too the Vatican; tsunamis engulf Asia; blazing meteors rain down on Yellowstone Park; a massive cruise liner turns turtle Poseidon-style — these are just some of the dazzling, Oscar-worthy special effects in co-writer-director Roland Emmerich’s extraordinary disaster movie. It says much for the actors, notably John Cusack as a father protecting his family and Danny Glover’s US President, that they are not overwhelmed by the spectacle. Thrilling and suspenseful.
