About Draper’s looks, aging, and weight gain:
Season 1 Don - note the jawline
Season 7 - very unflattering angle
To be clear, no blame. Aging happens, and the guy still looks handsome. He knows how old he is too. There was a serious fan push to cast Hamm as Clark/Superman for the Man of Steel reboot. Hamm was quoted quipping about how he’d be perfect for the part if they wanted to make a movie about an old, retiring Superman.
Don Draper would never grow a beard, but have you seen Hamm with one? It seems like whenever he’s not filming Mad Men, he knows that his beard compliments his jawline very well. It’s a great asset for many middle aged men, and it’s a hell of a more masculine alternative for actors than a facelift - which is seen on male celebrities way too often. Andy Richter has said that years spent sitting behind male celebrities on Conan, it was suprising how many actors had tell tale scaring from face lifts behind their ears.
