A Sound of Thunder Trivias

Production was slowed when severe floods in the summer of 2002 in the Czech Republic caused considerable damage to the set.

Filmed during the great floods of 2002 in Prague.

Renny Harlin left to direct the film Mindhunters (2004) instead.

This film was originally set for release in 2003.

Spota's supermarket is reference to Peter Hyams's wife's family name.

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.

Pierce Brosnan and director Renny Harlin were originally attached to this film.
