Jake Gyllenhaal: 'An Enemy' on the Run

Jake Gyllenhaal dashes across the street while filming a scene for An Enemy on Sunday (June 3) in Toronto, Ontario, Canada.

The 31-year-old actor can be seen on the big screen in a few months when his cop drama, End of Watch, hits theaters in September.

The film’s director, David Ayer, recently shared Jake was so convincing as a LAPD officer that even some real-life policeman were fooled.

He recalled one particular moment when Jake and co-star Michael Pena were in uniform sitting in a marked police vehicle with no cameras nearby to indicate a movie was being filmed.

“Cops in L.A. will do a hand sign with four fingers to say ‘everything’s good.’ Jake threw a ‘Code Four’ at some LAPD cops rolling by and they threw a ‘Code Four’ back. I don’t think they had any idea it was Jake Gyllenhaal!” David told Yahoo.
