Jon Hamm was so good on television’s Mad Men that some people still associate him with the enigmatic character he played, Don Draper. But he’s shown his versatility in a number of interesting films (like the new release Beirut) and revealed his flair for comedy, even hosting Saturday Night Live. He’s fun to talk to, as Leonard and Jessie can confirm—serious when the subject demands it and gloriously goofy when the mood strikes him. In other words, a perfect guest.
