The official synopsis for the film is as follows:
Caesar and his apes are forced into a deadly conflict with an army of humans led by a ruthless Colonel. After the apes suffer unimaginable losses, Caesar wrestles with his darker instincts and begins his own mythic quest to avenge his kind. As the journey finally brings them face to face, Caesar and the Colonel are pitted against each other in an epic battle that will determine the fate of both their species and the future of the planet.
While it’s mostly the same footage we’ve had before, there’s a few more action sequences added in (avalanche?) and more dialogue from the conversation it seems between Caesar and the Colonel. The film stars Andy Serkis, Woody Harrelson, Steve Zahn, Judy Greer, Karin Konoval, Terry Notary, Max Lloyd-Jones, Aleks Paunovic, Sara Canning, Gabriel Chavarria, Chad Rook and Amiah Miller.
War for the Planet of the Apes is scheduled for cinematic release on the 14th July 2017.
