New NBC entertainment chairman Robert Greenblatt is putting his stamp on the network’s development with a pilot order for a project he originally developed while at Showtime. NBC just greenlighted Smash, an ambitious one-hour musical about the mounting of a Broadway musical based on an idea by Steven Spielberg. The pilot, which will be produced by DreamWorks TV and Universal Media Studios, follows a cross section of characters who come together to put on a Broadway musical. TV writer/playwright Theresa Rebeck wrote the script and is executive producing with Spielberg, Darryl Frank and Justin Falvey of DreamWorks TV, Hairspray producers Craig Zadan and Neil Meron  and Grammy and Tony-winning songwriters Marc Shaiman and Scott Wittman who will pen original songs for the show. Negotiations are underway  for Michael Mayer (American Idiot) to direct. Smash joins an expansive slate at DreamWorks TV, which includes 4 series, including the upcoming The Borgias on Showtime and Terra Nova on Fox. Musicals have been a hot genre on the broadcast networks this development season with in light of the success of Fox’s Glee, but Smash is the first such project to reach a pilot stage.

Also greenlighted to pilot at NBC under Greenblatt is the comedy spec I Hate That I Love You, from Will & Grace alumna Jhoni Marchinko and 20th Century Fox TV. It is described as a twisty single-camera romantic comedy in which a straight couple introduces two of its lesbian friends to one another and what results is both instant attraction and a pregnancy.
