A Sound of Thunder is a 2005 science fiction film directed by Peter Hyams. The film was planned originally for a 2002 release. However, flooding in Prague (where the production was filmed) and other financial difficulties—including the bankruptcy of the original production company during post-production—resulted in a delayed release. A Sound of Thunder is based on the short story "A Sound of Thunder" by Ray Bradbury. The film is about "time tourists" who accidentally interfere too much with the past, completely altering the present.
