Writer/director David Ayer has more than a passing familiarity with the heroes and villains of law enforcement. He’s been behind the pen of Training Day, S.W.A.T., Dark Blue and Harsh Times, while stepping behind the camera for the latter film, as well as Street Kings. His latest effort, End of Watch, has him pulling double duty, but giving up some camera control to his principal leads Jake Gyllenhaal and Michael Peña. In bringing some aspects of “found footage” into an action movie following two street cops on their daily grind, Ayer has managed to find another layer of realism that makes his films so enjoyable. Hit the jump for our breakdown of End of Watch on Blu-ray, including the highlight of Ayer’s directorial commentary that makes the film easily worth a repeat viewing.
