The film, starring Jake Gyllenhaal and Michael Pena, has a found footage aesthetic but doesn't appear logistically bound to the style.  Gyllenhaal and Pena are two Los Angeles street cops who end up in a battle they can't possibly win against some unsavory gentleman who dabble in the illicit narcotics trade. 

That story is very much in the wheelhouse of David Ayers, whose credits as a writer and/or director include Harsh Times, Street Kings, Training Day, S.W.A.T., and Dark Blue.

Naturally, the movie carries on R rating on account of, "strong violence, some disturbing images, pervasive language including sexual references and some drug use."  You'll see much of that on display in this trailer, which is available in high definition at Yahoo! Movies, too.

The supporting cast here includes Anna Kendrick, America Ferrera, Frank Grillo, and Cody Horn.  I understand that this red band trailer is meant to communicate the hard edges of the movie, but to have Anna Kendrick in your movie and leave her out of any trailer entirely is folly, pure and simple.

Here's the official synopsis:

A powerful story of family, friendship, love, honor and courage, End Of Watch stars Academy Award(R) nominee Jake Gyllenhaal and Michael Pena as young Los Angeles police officers Taylor and Zavala as they patrol the city’s meanest streets of south central Los Angeles.

Giving the story a gripping, first-person immediacy, the action unfolds through footage from the handheld HD cameras of the police officers, gang members, surveillance cameras, and citizens caught in the line of fire to create a riveting portrait of the city’s most dangerous corners, the cops who risk their lives there every day, and the price they and their families are forced to pay.

End of Watch hits theaters on September 21st, and hopefully it will mark one more step on Michael Pena's march towards global movie stardom.  The guy is just fantastic, as evidenced by this clip from Observe & Report.
