The Classic Superman: Jon Hamm

He already has four years' experience playing a superman, albeit one of the Nietzchean variety: Mad Men's Don Draper says what he thinks, takes what he pleases, and charts his own path, all while living a lie from nine to five. We've even seen Hamm wear thick-rimmed glasses from time to time, not that he needs them any more than Clark Kent does — this is one actor who looks good in any kind of suit. At 39, however, Hamm may just be too old — or even too famous — for a role that has traditionally gone to relative newcomers.
