The biggest of the new wave of disaster flicks paying tribute to the Irwin Allen celebrity-fests of the '70s finds an alien armada descending on Earth to create some fireworks on the July 4th weekend. The fate of the world rests in the hands of an unlikely band of Earthlings led by President Whitmore (Pullman), a computer expert (Goldblum), and a Marine fighter pilot (Smith). Special effects, despite forgoing some of the more expensive newer technology, don't disappoint. Strong (if not A-list) cast and plenty of action. Devlin and Emmerich wrote the script while promoting "Stargate," after a reporter asked Emmerich if he believed in aliens.
