Jake Gyllenhaal teamed up with Michael Pena yesterday on the LA set of their police drama End of Watch. The actors modeled official police uniforms, and Jake debuted a freshly shaven face and head. He transformed into a similar look in 2005 for his role as a Marine in Jarhead. Production seems to be in the early phases for Jake, who just wrapped up an extensive promotional tour for Source Code, and Michael, who starred opposite Matthew McConaughey and Ryan Phillippe in The Lincoln Lawyer. Jake should feel comfortable back in the saddle for an action film with Source Code and Prince of Persia already under his belt.
