If anyone is expecting a remake of the Hal Roach classic with Victor Mature and Carole Landis or even the other version with Raquel Welch pass this Science Fiction channel special right on by. In fact passing it by on general principles might be a good idea as well.
100 Million BC starts in Philadelphia of all places with that famous and mysterious experiment that the city gave its name to in which a lot of navy personnel lost their lives and left no remains behind to tell a story.
Years later one of the survivors of the experiment, now grown a lot older and played by Michael Gross has been tinkering with the failed technology and believes what happened was these men and women had gone back in time, back in a lot of time it turns out to when dinosaurs roamed the earth. Of the fifty navy personnel that went back in time only a few have survived as Gross and another navy team come to rescue them. Among the survivors is Christopher Atkins now way beyond his Blue Lagoon boy toy days.
Gross brings a few back, Atkins included through a time portal, but also crashing through the portal is a mean and hungry tyrannosaurus rex. He's not liking his new neighborhood which is 21st century Los Angeles.
Maybe one day we'll actually find out what the real Philadelphia Experiment was all about. I can't believe it was this however. The science leaves a lot to be desired, the human actors look like they just collected their paychecks and went through the motions. When the computer animated T-Rex gives the best performance in the film, you know you've got a Thanksgiving feast on your hands.
