If you change something in the past, will it affect the present? "Yes!" says this eye-filling, time-travel thriller based on the classic Ray Bradbury story and directed by Peter Hyams (Timecop, End Of Days).

Chicago, 2055. Time Safari, Inc. led by its slick CEO (Ben Kingsley), offers the hottest ticket around: an expedition into the past to hunt dinosaurs. Just don't bring anything back. Someone does. And 65 million years of evolution jump the tracks. Vegetation engulfs buildings. Carnivorous insects attack. Highly evolved dinosaur descendants turn humanity from predator to prey. It used to be our world. Now it's theirs...unless two scientists (Edward Burns and Catherine McCormack) can somehow turn back the clock.
