John Lithgow's performance is excellent. He's been in a few stinkers where he overacts something fierce, but this is a very realistic portrayal.
Everything he does seems to result in an over-the-top farce, it would be refreshing to see an understated performance from him for a change.
I was going to see this, but decided to see Cowboys and Aliens instead. I had heard that the apes didn't look realistic at all, that in many ways the original movies with men in suits felt more realistic than a computer animation would.
If there are references to the first '68 movie, then I'd like to see it for sure!
