Looking for a Movie Title

[HeavenShallBurn]

After checking out Primeval I got a hankering for other such. Time travel related fare. And I'm remembering a movie from a couple years ago that involves traveling back in time to hunt dinosaurs. Where somebody steps off the path and does something that alters the timeline in the future. Where everything is changed and there are weird monsters running around. I think it was based on a short story, and I think it stared Val Kilmar though I'm not sure about the last part.

Does anybody know the title of this movie?

You're probably thinking of "A Sound of Thunder," which was a (very poor) adaptation of a Ray Bradbury short story.

Thank you.

Now that I've googled it maybe I should go looking for something else. God does that sound bad, they completely butchered Bradbury. Then again Hollywood tends to butcher every author.
