Travis, Sonia, and tech officer Payne (David Oyelowo) must make their way through flooded subway tunnels and battle a gigantic, anaconda-like mutated eel. Sonia jerry-rigs a power supply to send Travis back.

Writing in the aftermath of World War II and at the outset of the Cold War, Bradbury embeds the fear of anti-American authoritarianism in his text. Travis meets with Sonia Rand ( Catherine McCormack), the angry scientist who invented the technology, who explains that more changes will come via "time waves," wavy-shadowy effects that wash over the city. While A Sound of Thunder takes place in the 2050s, it is in many ways just as much about the concerns of the 1950s. When a time travel "jump" goes wrong, Chicago's winter days are suddenly balmy, trees grow through walls, pavement cracks, power goes out, and the city is devoid of people. Go-back team leader and scientist Travis Ryer ( Edward Burns) shows his distaste for the scheme, but goes along for the ride anyway. Based very loosely on a short story by Ray Bradbury, the movie's premise is that killing these mighty reptiles does not affect the future, but that the smooshing of a single butterfly causes havoc in 2055, the movie's present. In A SOUND OF THUNDER, ultimate corporate villain Charles Hatton ( Ben Kingsley) owns Time Safari Inc., an agency that sends rich folks back 63 million years so that they can shoot allosauruses.
