The series 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.
