Chicago, 2055. Charles Hatton has made a fortune by founding 'Time safari', which offers rich 'big game hunters' short time travels to kill off dinosaurs just before their natural death. When scientist Travis Ryer notices the weather and wildlife are not behaving as usual, he consults Dr. Sonia Rand, the contractually invisible inventor of the supercomputer which controls time. They soon face 'time waves', each worsening the effects in 2055 of evolutionary distortions, lower lifeforms first. They attempt to identify and rectify the past alteration, but each attempt gets harder in their distorted present. Written by KGF Vissers

Did You Know?


The change in the timeline is caused by a single butterfly. This alludes to the "butterfly effect", in which a small change in one state of a system can result in large differences in a later state. See more »


While one might expect that each group jumping to the same moment in the past (5 minutes before the volcano erupts) would in turn encounter all those from previous trips as well, adherence to such a claim would render the concept of time vacations completely unfeasible, and thus the film maker's decision to disregard this bit of logic is crucial to the film's coherency. This being said, Travis is only ever able to see himself and others by worm-holing to a point one year before the disturbance occurred and then slingshotting forward in time, not backward.

Slow death of a great story
27 August 2005 | by jdvargas15See all my reviews

Another awful adaptation of a great short story, this movies had some great potential thanks to the story its based on but it took a very very wrong turn somewhere along the way. The actors don't live up to my expectations there performance is unbelievable they could have just phoned it in an saved all of us a loss of time and money..i really didn't like this movie, after the acting started to bore me to death of i thought the special effects would pay the ticket but forget it they suck most of all, a wast of a very good piece of literature..Bradbury would also say this movie really really doesn't live up to expectations for his fans

If there is any other option at the multiplex take it!!!!
