I've been saying this for a while, but the new synopsis released by Fox at the start of production pretty much proves Dawn of the Planet of the Apes is a redo of the final original Apes film, Battle For The Planet Of The Apes.
A growing nation of genetically evolved apes led by Caesar is threatened by a band of human survivors of the devastating virus unleashed a decade earlier. They reach a fragile peace, but it proves short-lived, as both sides are brought to the brink of a war that will determine who will emerge as Earth's dominant species.
That's pretty much exactly like the premise of Battle, which some changes. In Battle Caesar leads a mixed society of apes and humans in the days after humanity mostly wipes itself out in a nuclear war. While inner strife between the races threatens to tear his society apart, Caesar must also contend with irradiated survivors living in a nearby city who threaten war. The movie's not as good as that description makes it sound, and I've always felt that it could use a nice redo.
There's more to Dawn than that synopsis says; there's also a struggle within the ape community as to who should be leader, and what the vision for the future is. That actually reflects Battle, which saw Caesar butting heads with gorillas, who wanted to enslave the humans.
The movie is shooting right now. I was lucky enough to get to be on the set for Rise of the Planet of the Apes; I'm not counting on another set visit, but a boy can dream. Then again, having been on an Apes set ever... that was already a dream come true.
