Ryan Gosling in a Hat on The Gangster Squad Set Pictures

Ryan Gosling kept his hat low while filming The Gangster Squad in LA this afternoon. He's been on set for the last few weeks sporting retro looks, though it's another of his recent costumes, his character from Drive, that's expected to be a popular Halloween costume this year. Ryan was back on set following an exciting opening weekend for another film, The Ides of March. The movie took the second spot at the box office behind Hugh Jackman's Real Steel, after plenty of press efforts from Ryan and his costar George Clooney. George premiered The Ides of March in NYC last week, and the duo stepped out to support the project on the West Coast in September. Now that the promotional push is over, George is taking some time off and vacationing in Mexico with girlfriend Stacy Keibler, while Ryan has been hard at work on his latest role.
