The guy who showed up to his Men's Fitness cover shoot sure looked an awful lot like Don Draper—brooding and dapper with slicked-back hair and a perfectly placed tie. But make no mistake, Jon Hamm is no Don Draper. "He couldn't be any more different from his Mad Men character," says Men's Fitness photo director Jane Seymour. "He was friendly, funny, laid-back, and very down to earth." In fact, Jane calls the shoot—at a school baseball field—our "most relaxed" one yet. On-set conversation ranged from how much Jon loved his rescue dog to his recent trip to India, where he filmed his upcoming baseball movie, Million Dollar Arm. In this exclusive behind-the-scenes video, Jon Hamm shares the most game-changing moment of his career, the best advice his teachers have ever taught him, and how he likes to stay fit.
