"Apes together strong." That's one message put forth by Caesar (Andy Serkis) in the full trailer for Fox's "Dawn of the Planet of the Apes," a sequel to 2011's "Rise of the Planet of the Apes." The other: "War has already begun." Sorry, well-meaning human beings played by Jason Clarke and Keri Russell! "Dawn of the Planet of the Apes" is out in theaters on July 11. Clarke, Russell, Serkis and Gary Oldman, as the Captain Ahab of this story, all co-star.
