Chimp Koba (Toby Kebbell) does not always agree with Caesar (Andy Serkis), and has his own ideas about how the apes can win their war against the few remaining human survivors in the second clip from Dawn of the Planet of the Apes. Koba wanders into one of the human camps, where he tricks two guards into thinking he's a circus performer, laughing and doing summersaults. Winning their trust, he's able to grab one of the guns, which doesn't end well for the two watchmen. Check out one of the more frightening scenes from director Matt Reeves's follow-up to 2011's Rise of the Planet of the Apes.

A growing nation of genetically evolved apes led by Caesar is threatened by a band of human survivors of the devastating virus unleashed a decade earlier. They reach a fragile peace, but it proves short-lived, as both sides are brought to the brink of a war that will determine who will emerge as Earth's dominant species.
