Smokin' hot! Ryan Gosling gets into character on the set of his new movie Gangster Squad



Ryan Gosling was on set in Los Angeles last night sporting a spiffy fedora and pin-striped suit for his role as a suave Forties cop in his new film Gangster Squad.



The movie, also starring Emma Stone, Sean Penn and Josh Brolin, is a chronicle of the LAPD's fight to keep East Coast Mafia types out of Los Angeles in the 1940s and 50s.

The Crazy, Stupid, Love star plays Sergeant Jerry Wooters in the film, about mobster Mickey Cohen, part of the Jewish Mafia.
