Ben Affleck’s directorial debut, Gone Baby Gone, opens this week. It’s set in a rough-and-tumble Irish neighborhood in Boston — the same setting as Clint Eastwood’s Mystic River and Martin Scorsese’s The Departed. Studio 360’s Eric Molinsky looks into why his hometown of Boston (and specifically the areas of Southie and Dorchester) keeps getting treated to these class-centered cinematic portraits.
