What I thought was so great about Rise [of the Planet of the Apes ] was that it wasn't a retelling; it was an entering of the universe at a different point. So it's Planet of the Apes. We already know the ending. There's no mystery in that! It becomes Planet of the Apes. So it's not about what is at the end; it's about how did we get there? And that enabled something that was totally fresh, which was an ape-point-of-view movie.
