Gangster Squad may be about the takedown of a mob king played by Sean Penn, but if the poster is any indication, the real stars are Crazy, Stupid, Love alumni Ryan Gosling and Emma Stone.

The poster for the September 7 film was just released, with Josh Brolin and Penn flanking the hot squad of Ry & Em.

According to Flicks and Bits, Gangster Squad is a fact-based tale derived from a series of articles by Paul Lieberman. The story follows "the crime fighting exploits of a squad of elite Los Angeles officers in the 1940s, led by Josh Brolin’s Sgt. John O’Mara and Ryan Gosling’s Jerry Wooters, charged with stopping ruthless Brooklyn-born mob king Mickey Cohen (Sean Penn)."

Watch a preview for the film below — and get ready for things to heat up for RyEm.
