Thanks for the Memories
17 August 2013 | by jcook56050See all my reviews

No, not the absolute best movie that could have been made given the resources available to the film makers, but definitely a different approach for a relatively new format - i.e. 3D IMAX size. Compared to some the things that had been done by Douglas Trumbull for the likes of Universal at a very high budget, this motion picture was quite passable for a production done on the cusp of the CGI era. And, IMAX had a tendency to hire actors who were capable of telling the story rather than distracting from the ultimate goal of education.

Let me warn you that the subject matter is educational and meant to evoke some of the possible theories and realities of palaeontology. Much of what IMAX produced for decades filled in the scientific genre of big screen learning before the Discovery Channel had hit its stride. The producers were very limited by the size of the equipment and the resultant technologies needed to bring this very expensive experience to the very large screen. These days, of course, you can do a 3D motion picture using a film camera that practically fits in the palm of the hand.

Now on to something I'll bet very few folks recognize in the story line. Listen to Ally's experience in the museum, and some of you may realize that she is either a full blown diabetic or somewhere on the edge. Many kids have this problem, and it's a real limiting factor when you go out there on a professional dig where it's possible to get lost in the canyons of the west when being overtaken by low blood sugar. It clearly explains why her father is reticent to take her on a dig. Despite his seeming distraction with work, he really does care about his daughter's well being.

Finally, I want to thank the film makers for the location of their shoot. Anyone who dares to travel the badlands of Alberta, Canada, will not regret taking a trip to Drumheller to see the world's greatest palaeontology museum, The Royal Tyrell. We've never seen anything that gets near to the quality of displays and historical information as this amazing organization. Both my wife and I have been to all the filming sites used in the motion picture, including the preparation rooms (minus the little changes they made for the film). It brought back some incredible adventures to our memory. It's the only place I know of where a walk of 100 feet will transport you one million years into the past.
