Marshall could not confirm to Playbill On-Line the casting of the central role of Princess Winnifred (which Burnett originated on stage and subsequently played in 1964 and 1972 TV films), but reports have placed Hairspray's Marissa Jaret Winokur in the role.

The TV film would mark Marshall's small-screen debut as a director. She previously provided the choreography for a 2003 TV version of The Music Man starring Matthew Broderick and Kristin Chenoweth.

Production and air dates have yet to be announced.

Once Upon a Mattress, which is essentially the fable of "The Princess and the Pea" set to music, marked Burnett's Broadway debut, and her role as the comical Winnifred became one of Burnett's signature parts. Featuring a score by Mary Rodgers (music) and Marshall Barer (lyrics) and a book by Barer, Jay Thompson and Dean Fuller, the original Broadway company also included Jack Gilford, Joe Bova and Jane White. The 1996 Broadway revival featured "Sex and the City" star Sarah Jessica Parker in the role created by Burnett with co-stars David Aaron Baker, Jane Krakowski and Mary Lou Rosato.
