A huge comet is on a collision course with Earth in director Mimi Leder's science-fiction disaster movie, which gains a certain amount of credibility by highlighting the human side of the impending catastrophe. The frightening scenario focuses on TV reporter Téa Leoni, who stumbles upon the story while tracking down what she thinks is a Presidential indiscretion, and astronaut Robert Duvall, who leads a mission to intercept the threat in space. The chilling gravity of the situation is hauntingly evoked by the national lottery that's put in place to choose who will "survive" in an underground retreat. Leder adds gripping immediacy to executive producer Steven Spielberg's loose remake of Rudolph Maté's 1951 movie When Worlds Collide and caps it all with a spectacular display of epic destruction.

A seven-mile-wide space rock is hurtling toward Earth, threatening to obliterate the planet. Now, it's up to the president of the United States to save the world. He appoints a tough-as-nails veteran astronaut to lead a joint American-Russian crew into space to destroy the comet before impact. Meanwhile, an enterprising reporter uses her smarts to uncover the scoop of the century.
