FILM 1533: END OF WATCH
TRIVIA: As part of their training, Jake Gyllenhaal and Michael Peña spent five months doing 12-hour ride-alongs with on-duty LAPD officers. During Gyllenhaal's first ride-along, he witnessed a murder.
The scene where Janet and Brian are singing in the car during a road trip was unscripted. Jake Gyllenhaal and Anna Kendrick were driving around with the director in the back seat filming different scenes for the movie. At one point between takes, 'Hey Ma' by Cam'ron came on the radio and Gyllenhaal and Kendrick started to sing along and the director began to secretly film them. Both Gyllenhaal and Kendrick were completely unaware that the moment had been caught on camera until they watched the movie at a screening.
