A Sound of Thunder written by Ray Bradbury movie was about a guy who stepped on a butterfly and went back in time to fix things. The movie was very interesting but some of the acting was bad. The movie and the short story was similar but I liked the movie better.The movie was better because it had more action then the story. The story was boring I would never read that ever again. I would watch the movie again because it was a great movie. I highly recommend this movie to others. I give the movie a thumbs up. I give the story a a thumbs down.
