Why Joan Is So Mean To Peggy In Mad Men

While it's easy to talk about Jon Hamm's Don Draper as the protagonist of Mad Men, the TV show owes a lot to Elisabeth Moss and Christina Hendricks. Playing Peggy Olson and Joan Holloway Harris, respectively, the actresses were a huge part of what made Mad Men work. However, Peggy and Joan were far from friends at first. As two of the few women at Sterling Cooper, the ad agency the series follows, who gained success and respect, there were many instances throughout Mad Men when the pair were at each other's throats.
