Not much has been said about it, and it should be said: Jon Hamm did something pretty unbelievable this week. Just 24 hours after the sensitive news broke that he had finished a stint in rehab, Hamm showed up for a full day of press, promoting AMC’s final season of Mad Men , which comes back April 7. Many actors…most actors…would not do that. In good spirits, and joking that he’s part of a secret society of hot, bearded, Hollywood men, Hamm tackled some serious questions about what Don Draper deserves in the very end, and how working on yourself is important for the people you love.
