End of Watch is a 2012 American action thriller film written and directed by David Ayer. It stars Jake Gyllenhaal and Michael Peña as Brian Taylor and Mike Zavala, two Los Angeles Police Department officers who work in South Central Los Angeles. The film focuses on their day-to-day police work, their dealings with a certain group of gang members, their friendship with each other, and their personal relationships. Ayer, who had written several police procedural films previously, wanted the film to focus more on the friendship between partners and daily police work and subordinate the contextual elements of the drug trafficking story taking place on the streets of south-central Los Angeles.
