So how did a girl from Queens master Boston's difficult dialect? "Well, I had [co-star Casey Affleck] and Ben on both shoulders, and Ben cast a lot of nonactors and local actors in the films," she says. "Mostly it's by listening. I think that the best lesson as an actress is just to observe as much as you can. So I would just keep an ear out to anything authentic."
Amy said maintaining the accent could be tricky, but she always stayed in it on set. "I didn't want to stick out. I prefer to hide away into roles and let the character play through me rather than move in," she says.
