JON HAMM and ROSEMARIE DEWITT
AMC’s Mad Men began airing in the summer of 2007, but this year it became absolutely unacceptable not to be obsessed with all things Don Draper and the man behind him,
Jon Hamm. The debonair actor has been working steadily for years, but suddenly came out of nowhere to land a
GQ cover and the heart of every woman in America whose heart formerly belonged to George Clooney. Meanwhile, Hamm's onetime Mad Men co-starlet, Rosemarie DeWitt, went on to have her own stellar year. She stood out in Rachel Getting Married in the title role, and landed a main part in Diablo Cody’s new Showtime series, The United States of Tara. See her in two starring roles in 2009, and on just about every “hot list” of magazines that can still afford to print.
