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 .
