Books like a sound of thunder

A Sound of Thunder is a 2005 science fiction thriller film directed by Peter Hyams and starring Edward Burns, Catherine McCormack and Ben Kingsley. It is a co-production film between the United Kingdom, the United States, Germany, and the Czech Republic.

The film is based on the 1952 short story of the same name by Ray Bradbury. It is about "time tourists" who accidentally interfere too much with the past, completely altering the present. It failed at the box office, earning $11 million against a production budget of $80 million. It received negative reviews from critics.

In the year 2055, the Chicago-based Time Safari company offers the opportunity for rich people to hunt dinosaurs in the past via time travel technology. As a precaution against the potential change of the past, the company preys only on the dinosaurs who would otherwise die of natural causes and keeps the clients from stepping off the designated path. Because of the dangers of interfering with the timeline, the company's activities are vocally criticized by Sonia Rand, the developer of the time machine software "TAMI", who feels disappointed for not receiving credit during her work and is worried that some clients may alter the past through their activities.
