This comes rather late, considering that The Butterfly Effect was “hooted off the screen” weeks ago, but for those of you who are still unaware of the reference, the original “cumulative-effects” concept of time travel was first popularized in Ray Bradbury’s 1952 short story A Sound of Thunder. I hear that a Sound of Thunder film is in the works for later this year. (Of course, there was also Treehouse of Horror V with Homer and the Time Travel Toaster.) More on that from the Time Travel Reviews at Andy’s Anachronisms.
