"Mad" Man To Play "30 Rock" Love Interest

LOS ANGELES — Jon Hamm is temporarily trading the offices of Sterling Cooper for "30 Rock." The actor, who plays advertising executive Don Draper on AMC's "Mad Men," will portray the love interest of Tina Fey character Liz Lemon _ a doctor who lives in her apartment. Could it last? "I just finished a couple of episodes, and I'll go back in the new year and do another one of those, and then we'll see what happens," Hamm said Tuesday at a benefit for the UCLA School of Theater, Film and Television. ___ On the Net: http://www.nbc.com/30_Rock/ (link)
