Jon Hamm explains how he approaches every new season of Mad Men: “I honestly don’t like knowing what’s going to come down the pike, for fear of somehow subconsciously playing the end of the story, or playing information my character shouldn’t have. That said, Matt and I sit at the beginning of every season and we talk about what the season is going to bring and what the arc of the season could be or should be or might be — but this is well before anything is written. And we talk in very, very general terms of themes and feelings and general ideas.”
