On Monday night, the stars of "End of Watch" hit the red carpet to celebrate the premiere of their film.

After a routine traffic stop, a police team (Jake Gyllenhaal and Michael Pena) is marked for death by a Mexican cartel. From David Ayers, the film uses gritty found-footage and security cameras to give you an up-close-and-personal view of the real life dangers on the force.

Gyllenhaal spoke with Moviefone at this year's Toronto Film Festival about what it took to prepare for his new action film.

"We went on ride-alongs for five months, two to three times a week with the LAPD and sheriff's department and Inglewood PD. We would work with them from about 4:00 p.m. to about four or five in the morning. Then we did tactical training about two or three times a week with live ammunition and training exercises, then fight training almost every morning with [director] Dave Ayers's best friend, who has a dojo, getting the crap beat out of us by 14 to 20-year-old kids. That coupled with rehearsing on our time off and just spending time with [co-star] Mike [Pena] out of work and getting to know each other."

The stars of the film -- Gyllenhaal, Anna Kendrick, Michael Pena and America Ferrera -- were all in attendance at last night's event. Take a look at the red carpet pics below.

"End of Watch" hits theaters September 21.
