In many cases, the performances — particularly Affleck’s — started with questions. “Casey is great to work with, because he’s very demanding about all the right things,” Lonergan said of his leading man. “
He really wants to know specifically why something is happening, when it’s happening, why something else isn’t happening, why his manner is like this with one person but not another person. Exploring all those subtleties and specifics with an actor is really fun. Plus we like to yell at each other.”
