2055, Charles Hatton has made a fortune by founding 'Time safari', which offers rich 'big game hunters' short time travels to kill off dinosaurs just before their natural death. When Travis notices the weather and wildlife are not behaving as usual, he consults Dr. Rand, the contractually invisible inventor of the supercomputer which controls the time travel. They soon face 'time waves', each worsening the effects in 2055 of evolutionary distortions, lower lifeforms first. They attempt to identify and rectify the past alteration, but each attempt gets harder in their distorted present. Written by KGF Vissers

Mediocre film about time travels with several terrifying animals and a lot of of C.G.I.
28 June 2006 | by ma-cortesSee all my reviews

2055 , Chicago , Charles Hatton (Ben Kingsley) an avaricious tycoon is an owner of a valuable enterprise about time machines called Tammy that is converted in a time traveler towards the Jurasik and carrying rich tourists to kill dinosaurs . Hatton receives his clients after their time safari and he likes to compare them with great explorers : Marco Polo , Christopher Columbus , Armstrong and others . Travis (Edward Burns) is a resourceful scientist at charge of the risked hunting . Scientist Sonia Rand (Catherine McCormack) as invention creator warns the dangerous experiments . Thus , the machine cannot ultimately control itself and it is created a time wave similar to Tsunami which changes the earth . Then , it appears various predator animals and colossal carnivores , humans try desperately escape of weird animals and they are chased by fanged giant creatures through a leafy vegetable city .

This thrilling sci-fi picture blends suspense , tension , bone-chilling scenes , genuine scares and amount of images have you on the edge of your seat . Abundant special effects are generally made by computer generator , as it is well reflected on an amazing array of technical bizarre creatures , such as : prehistoric Allosaurius , giant eel, mutants animals , ferocious and carnivorous plants and insects developing a bloodthirsty hunger . The film is based on a Ray Bradbury novel , a short story titled ¨A Sound of Thunder¨ but are modified some deeds , in the book the fatal accident is produced during the presidential election and the winner results to be a fascist candidate , while the movie is narrated in actioner as well as spectacular style . The picture was averagely directed by Peter Hyams (replacing Renny Harlin who was fired from the producers for disagreements with Ray Bradbury) , though production was slowed when severe floods in the summer of 2002 in the Czech Republic caused considerable damage to the set . One major reason for the film's long delay is that the original production company went bankrupt during post-production , and there simply wasn't money to finish the film . Director Peter Hyams is a nice filmmaker and usual cameraman of his films , realizing good Sci-fi titles (¨Capricorn one¨ , ¨Outland¨) and even a similar movie about time travels , but better directed , such as ¨Timecop¨(1994) with Jean Claude Van Damme . Atmospheric musical score fitting to action by Nick G. Smith . The movie failed in the box office and was exhibited in 2005 , two years later its shooting . The movie was filmed in Republic Czechoslovakia with difficulties but had a lot of floods in Praga . Rating : Average but entertaining .
