STAGE TUBE: Katharine McPhee Visits THE VOICE to Preview SMASH!

The show, which is about a group of people who come together to put on a Broadway musical was developed by NBC's Robert Greenblatt, Steven Spielberg, and Broadway producing team Craig Zadan and Neil Meron. Broadway's Marc Shaiman and Scott Wittman - whose latest venture, CATCH ME IF YOU CAN, is now running at the Neil Simon Theatre - wrote the music for the show. Michael Mayer directed the project, and playwright Theresa Rebeck penned the script.

The plot will follow an out-of-town tryout of a Broadway musical, and centers around a songwriting team (Debra Messing and Christian Borle) who write a musical about Marilyn Monroe based on an offhanded remark. They post a showstopping number on YouTube. When it's a viral hit, a producer (Anjelica Huston) who's looking to recapture success long past decides to produce the musical. There are two choices to play Marilyn: Karen (Katharine McPhee), a talented young newcomer, and Ivy (Megan Hilty), a theater veteran. Brian d'Arcy James has also been cast as Debra Messing's character's husband.
