An IMAX 3D must see!!
11 October 2002 | by Mark-HSee all my reviews

If you haven't yet seen an IMAX 3D film this is the one to watch!

Ally (Liz Stauber) works in the natural history museum and wants to be a paleontologist like her Dad (Peter Horton). When her Dad returns from a dig with what she believes could be a T-Rex egg, a mishap leads to toxic fumes escaping from the 'egg' which Ally accidentally breathes, taking her back in time into a fantastic example of the IMAX 3D experience through her hallucinatory journey.

The 3D effects are stunning, from the archaeologists chipping away at the rocks apparently sat on your knee to the amazing close-ups of the pre-historic creatures as they appear just inches from your face!

If, like me, you feel that the average film is too long, then you'll love this. At around 45 minutes, it's more like a long TV program than a movie so there's no chance of boredom setting in, and the continuous 3D effects throughout will leave you grinning with awe and enjoyment.

Sure, it isn't Jurassic Park, but for a short, and presumeably low budget movie with a relatively unknown cast, the effects are very good indeed and the story is simple, but nice.

This film really needs to be viewed as it was intended to be though, in 3D, so that the effects come to life and engross you into feeling you are there.
