Years ago I read a short story, it was set in the future and a company was offering time travelling 'big game hunts', transporting people back to shoot dinosaurs. A man slips from the pathway and crushes a butterfly which really messes up the future. Can anyone please tell me what the title was as I'm dying to read it again! Please Please Please of you know what I'm talking about, let me know at taller_mike@hotmail.com

That would be A Sound of Thunder. Root around on this site for the threads discussing the movie based on this short story to be released in September.

Best,

Pete
