In this action-packed comedy from the director of GHOSTBUSTERS, a firefighting cadet, two college professors, and a geeky government scientist work against an alien organism that rapidly evolves after a crash landing on Earth. Before long the creatures are growing at an exponentially rapid rate, resulting in fearsome aliens running amok and possibly spelling mankind's doom--or at least the end of man's domination over life on Earth. David Duchovny, Orlando Jones, Seann William Scott and Julianne Moore star in this non-stop special effects blockbuster that includes an appearance by Sarah Silverman.
