When “Alfie” and “Factory Girl” actress Sienna Miller was cast as Catherine Greig in the big-budget adptation of “Black Mass,” we were skeptical about whether the 32-year-old actress could really age up to play Whitey Bulger’s longtime partner in hiding. But Miller looked altered enough when she was dressed as Greig during the shoot in Quincy on Tuesday. Passersby said the crew filmed the Bulger arrest scene that day. The film’s Whitey, Johnny Depp, was spotted on location wearing a white bucket hat (the kind of hat that Gilligan wore on the island). Miller is the third Whitey love interest we’ve seen during the shoot. Dakota Johnson was in town last month to play Lindsey Cyr, and English actress Juno Temple was in Lynn to play Deborah Hussey. “Black Mass” is being directed by Scott Cooper, who made “Crazy Heart.”
