Jake Gyllenhaal and Michael Pena End of Watch Pictures in LA

Jake Gyllenhaal carried a gun and cautiously approached a car as he filmed End of Watch on location yesterday. He was back in uniform with costar Michael Pena for another intense day fighting faux crime on the streets of LA. The guys suit up for the film, but Jake's six-pack and ripped muscles were on full display during his recent shirtless swim in Hawaii. The guys have been holding down the fort while Jake's onscreen love interest, Anna Kendrick, wraps up another role in Atlanta. She's among the long list of actors starring in What to Expect When You're Expecting like Jennifer Lopez, Cameron Diaz, and Brooklyn Decker.
