Photo Flash: Uma Thurman Channels Marilyn on Tonight's SMASH

On tonight's episode of SMASH entitled 'The Movie Star', "Bombshell" is turned upside-down by the arrival of movie star Rebecca Duvall (special guest star Uma Thurman). Karen (Katharine McPhee) and Ivy (Megan Hilty) are drawn into an uneasy alliance against their new rival -- but can they overcome their history? The romance between Tom (Christian Borle) and Sam (Leslie Odom, Jr.) heats up, while Julia (Debra Messing) and Frank (Brian d'Arcy James) must put aside their differences to address a family crisis. The episode airs Monday, April 16 at 10:00 pm/ET on the NBC network.

Thurman said of her character: "Rebecca Duvall is such a unique character.  She brings a new dynamic onto set and causes drama everywhere she turns.  'Smash' is such a huge production, with wonderful original songs and fantastic choreography. I hope 'Smash' fans will enjoy watching Rebecca as much as I enjoyed playing her."

SMASH stemmed from an idea of executive producer and multiple Emmy and Oscar winner Steven Spielberg ("ER," "Schindler's List"). The pilot was written by acclaimed playwright/screenwriter Theresa Rebeck ("Mauritius," "NYPD Blue"). David Marshall Grant ("Brothers and Sisters"), Craig Zadan and Neil Meron (Oscar-winning "Chicago," "Hairspray") and Darryl Frank and Justin Falvey ("United States of Tara," "The Borgias") also serve as executive producers. Original songs are written by Tony and Grammy Award winners Marc Shaiman and Scott Wittman("Hairspray," "Catch Me If You Can"), who serve as executive producers as well.

SMASH is a production of Universal Television in association with DreamWorks Television and Madwoman in the Attic. The pilot was directed by Tony Award winner Michael Mayer ("Spring Awakening," "American Idiot")
