Gummer, the daughter of Oscar winner Meryl Streep, will play the daughter of Eileen (Angelica Huston) and Jerry (Michael Cristofer) on the series.
"Smash," created by Theresa Rebeck (Seminar) and featuring a star-studded cast of Broadway performers, will include original songs written by Marc Shaiman and Scott Wittman (Hairspray, Catch Me If You Can).
The pilot was directed by Tony Award winner Michael Mayer (Spring Awakening, American Idiot) and was shot in New York City.
The series, according to NBC, "centers on a desire to create a Broadway musical based on the life of Marilyn Monroe—written by the successful songwriting duo of Tom (Christian Borle) and Julia (Debra Messing). Julia recently began the process of adopting a child with her husband of many years, but her focus is torn when she has the opportunity to write another Broadway hit. A rivalry soon forms for the lead role between a youthful, inexperienced Midwestern beauty (Katharine McPhee)—who is trying to find fame in the big city against all odds—and stage veteran (Megan Hilty), who's determined to leave the chorus line and finally get her big break. A tenacious producer Eileen (Huston) discovers the 'Marilyn' project and jumps on board with a brilliant director (Jack Davenport)—whose talent is matched by his cunning and egocentric amorality."
"Smash" will launch on NBC Feb. 6, 2012, at 10 PM ET.
