One of the key elements of difference between "Rise of the Planet of the Apes" and the recent sequel "Dawn of the Planet of the Apes" was the ten year time jump. Director Matt Reeves, already confirmed to be helming the third film in the series, says the next instalment will not feature such a major leap forward. He tells The Playlist:
"I don't necessarily think that there will be as big a leap between films. I see Caesar as a seminal figure in ape history and he's a mythic character.
He's essentially like their Moses and I think Caesar having to grapple with what it means to engage in this conflict that he doesn't really want to be a part of and how that cuts at his core is going to be one of the great challenges for the character.
I also think it's a generational story. He has children and I think it's going to be... to me there are many chapters of this mythic ape journey towards the original 1968 movie."
This matches with comments from Fox and others involved with 'Dawn' who see a rosy future for the franchise and one that doesn't have to rush to get to the point of the ape civilisation we see in the 1968 film.
