Early On-Set Alzheimer's

I haven’t seen Rise of the Planet of the Apes, but I have seen the trailer. Judging from the trailer, the plot goes something like this:

Scientists are working on a cure for Alzheimer’s disease and stumble across a drug which causes the human brain to repair itself. Great. Naturally, they try it out on chimpanzees first, and wow! - imagine their surprise when their star test chimp actually starts getting smarter. And smarter. In fact, pretty soon the monkey starts getting able to do pretty much everything a human can, and forms a close bond with its scientist owners. One of these guys, played by John Lithgow, actually has Alzheimer's, so there is a nicely poignant moment of ships passing in opposite directions as the chimp gets smarter, whilst the human is actually losing his faculties. I think I’m going to cry at that point. Anyway, for one reason or another, the drug doesn’t get approval. It’s possibly something to do with aggression caused in animal subjects. When our hero chimp violently intervenes in an argument and kills a human, he is locked back up in the lab, and the plug is pulled on the whole project. Enter some Stupid Humans who love taunting animals and want to show them who’s boss. Their recklessness causes the clever chimp to escape, and he administers the smart drug to all the other chimps, who then escape and proceed to take over the world.

Close enough? I’d be surprised if I have veered from the plot in any significant way. The relatively new trend of cutting trailers so that they not only give you a taster of the film, but also give you a taste of acts one, two and three, in that order, before hinting at an inevitable conclusion, all but makes going to see the actual film a mere formality, and a predictable one at that. The only way I'm now going to enjoy Planet of the Apes is if I get Alzheimer's before it comes out, and forget what I saw in the trailer. Needless to say, that will mar my enjoyment somewhat. People used to say “I hope the movie is as good as the trailer.” Now, it’s more relevant to say: “I hope the movie isn’t just a longer version of the trailer, but not as good, like with Iron Man 2 and several other releases in the last year or so.”
