A Sound of Thunder

“Some rules should never be broken.”

Travis Ryer (Edward Burns) guides wealthy clients back to the prehistoric era, where they pay to hunt a dinosaur under strict rules about where they may step. Peter Hyams, adapting the 1952 Ray Bradbury story, follows Travis as one stray footprint off the path sets off a chain of changes in the present. Sonia Rand (Catherine McCormack), a scientist who works alongside him, is the one he leans on as the world around them keeps shifting.
