I had a major problem with this movie for one reason. What did Red Leaf want the Tasmanian Tiger for? They were willing to spend a lot of money, and take extreme measures to get the DNA. But what could be so valuable about it? And how would they know anything about the DNA since they'd never had any before? If it was just to try and clone them, I don't see why they were being so ruthless to get it. It just seems like a lot of drama to get something that is never even stated as a motivation.
The motivation is stated clearly in the film. Jarrah was leary of Red Leaf because the tiger supposedly possessed a toxin it used to paralyze its prey, and Red Leaf wanted it--pretty obviously to militarize it. So, clone the animal, get the toxin, study it, mass produce it, sell it as a weapon. Simple. I don't see what you don't get. The problem with the film, contrary to the assessment of the poor soul who wrote the summary review, is that it is horribly predictable, at EVERY step, including the outcome, which I suspected in the first five minutes, and knew for certain when Jarrah turned out to be an eco-defender. Simplistic and, scenery aside, a waste of time unfortunately.
But how would they know anything about the toxin itself without ever having seen it or its effects? There are many other toxins already available that are known. How would they know that this toxin is worth all the effort?
Companies routinely spend millions on unproven technology or yet to be discovered medical breakthroughs every day. Big Pharm chases intelligent hunches and invests millions on cancer research not to hopefully ease pain and suffering but to eventually make billions in profits. Besides, there are almost always unintentional discoveries along the way that prove beneficial.
