There is no rest for Matt Reeves, the director of Dawn of the Planet of the Apes. Reeves is hard at work writing the next film in the series which he will also direct for an anticipated July 2016 release date.
In an interview with Meredith Woerner of io9.com, Reeves gave some hints as to which way Caesar and his ape kingdom will be heading.
In Dawn and Rise, Caesar is portrayed as a Moses-like figure leading his apes to freedom and a promised land. The two features are hinting at the introduction of an ape religion.
He becomes a very mythic character. And he's the Caesar that shall begin other Caesars. Given that we know the ending of the story and we know that Caesar has these ties to humans and to apes, and that everything gets really turned upside down by the world of the '68 film…
The question is how do we get there? And this then becomes a generational story. A story of not only Caesar and his family, but his children and how this story continues down that path. How Caesar becomes the first, truly mythic god-like character for the apes. He's very seminal figure for the apes. The idea, the objective for the story was to being the beginning of that mythic status for him. He goes from being a kind of revolutionary to a kind of leader to a mythic god.
Reeves explains where he sees the apes culture heading towards.
There's an important moment in the movie where Caesar admits that as much as he felt he was human, and as much as he felt that [James] Franco was his father and he had this connection to humans, in discovering what he was and returning to being an ape and freeing those apes from their bondage and beginning a civilization together — fulfilling that family in a way that he never really quite had when he was young — he really came to believe that apes were better than humans. And would not suffer a similar fate.
The big revelation for him in a very "through the looking glass" science fiction way was just how human the apes are. They came to realize what their limitations where their failing their ability to lose control. To sort of lose their ability to resist violence.. Caesar's constantly struggling against his violent impulses.
Now we start to go into this place where self preservation starts to be the order of the day. He knows there's no going back and explaining, "the apes didn't really mean to attack the humans, they were misled by a rogue ape." That's not something you can really explain to a society. And he realizes that now he has to grapple with the reality. He's got pulls in both worlds, this is going to be a very painful journey for him, and for the apes.
