I watched A Sound Of Thunder, starring Edward Burns and based on a Ray Bradbury. Burns works for a time-travel adventure company called Time Safari, and one of the jumps goes horribly wrong.
First of all, this movie is very good. The effects are great, the acting is good, the plot is interesting and everything meshes well. I just have two issues with time-travel-based logic.
*SPOILER START*
1. It would seem impossible to go back into the same exact spot in time more than once. Wouldn’t you see the other people? I’m not entirely sure what happened in the “slingshot jump” that was different than the other jumps. I mean, they went to the same instant and the same spot. Did jumping forward erase that in some way?
2. The future would be changed from that particular moment on, not through waves. As seen in Back To The Future, the travelers would encounter an entirely different world and people with no knowledge of anything different. While the waves added some nice effect, they forced me to suspend the laws of nature even if I ignored the actual time travel.
*SPOILER END*
All told, this is a great movie and I highly recommend it.
