The show must go on: NBC's renews `Smash' NBC's theatrical drama `Smash' is getting a curtain call. The show, which follows the production of a musical about the life of Marilyn Monroe, has been renewed for a second season. "Smash" made its debut in early February and is averaging about 7.7 million viewers. However, it is the network's highest rated drama among adults 18-49 and attracts a desirable audience for advertisers. The show's stars include Debra Messsing, Katherine McPhee and Jack Davenport. Given that the show's producers include Steven Spielberg and that it is a pet project of NBC Entertainment chief Bob Greenblatt, the renewal was not really a surprise.
