Time Travel To Feature in Dawn Of The Planet Of The Apes?

"I don't foresee that ... it's the one big element that we made a conscious decision not to explore in the first one, and we were worried that there might be some backlash in the science fiction community because of it. When the story first came together we were very, very excited, and yet before we pitched it, I thought, 'The one thing missing though is time travel. But it's not necessary for this particular telling'. And I don't really foresee it, to tell you the truth."

Given Jaffa's words and considering both Rise and Dawn are prequels to the events originally depicted in Planet of the Apes it seems there may be a few more stories to be told yet before we get to that iconic image of the Statue of Liberty buried deep in the sands of time. Source: Blastr
