While searching for other stuff, I stumbled across a UK website with an amateur movie based on A Sound of Thunder. To view the whole thing you need to register (which is free - scroll to the bottom of the page for this).

Here's the page: http://www.videotutor.co.uk/lastindependent/indexLI.htm

P.S. Although I am by trade a Video Tutor, I have no connection with the above site!
