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 Travis notices the weather and wildlife are not behaving as usual, he consults Dr. Rand, the contractually invisible inventor of the supercomputer which controls the time travel. 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?


This film was originally set for release in 2003. 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.

Travis Ryer: Some things to remember us by: A safari suit, boots, helmet and a holo-disk so you can relive the jump. And I suggest you take an especially close look at this disk, Mr. Wallenbeck.
John Wallenbeck: Why's that?
Travis Ryer: Well I can't be certain until I review it myself, however, I'm pretty sure it was your shot that brought him down.
John Wallenbeck: [laughs] Well, yeah.

Wow, can't believe I wasted 2 free movie tickets on this one
4 September 2005 | by (United States) – See all my reviews

I saw the movie poster for this and read a blurb, and though cool, my wife and I love action adventure sci-fi flicks. I ended up getting 2 free movie tickets from work and thought I'd take my wife to see this... What can i say? this movie is bad. Many times my wife and I snickered as the FX were not much better than what most any college kid with can do with their computer, a green blanket and a MiniDV cam. It was like watching something on Sci-Fi Channel at 1am on a slow holiday at home. the people in front of us got up and left, and never came back. there were only 8 or 9 of us in the theatre to begin with and there were only 2 times for this Film, which should of warned me especially since I had never seen any commercials or trailers for this ever before.

Sure there are some parts that were cool, and some interesting tidbits, but they were hard to follow. I am saddened that this guy Peter Hyams took a good story by Ray Bradbury and turned it into this crud.

Yep, this was at least a D movie... D for Dumb, Dismal, Disappointing, and D for Don't Go see this. If you like low end Movies go rent one at your video store or turn on your Cable TV.
