Hall will be interviewed by host Emily Frances about returning to the New York stage during the 8:30-9 AM half-hour. Hall recently ended his Emmy Award-nominated turn as David Fisher in the HBO series "Six Feet Under," a role he landed right after his Emcee duties in the Roundabout's revival of Cabaret. The actor — who did a stint on Broadway in Chicago opposite his wife Amy Spanger during the show's hiatus — has also appeared onstage in Skylight, Corpus Christi, The English Teachers, Cymbeline, Macbeth, Henry V, Timon of Athens, Romeo and Juliet, Much Ado About Nothing and Camelot.

Michael Greif (Rent) directs the new comedy by Noah Haidle which began previews Nov. 1 and opened Nov. 20 at Roundabout Theatre Company's Laura Pels Theatre in the Harold and Miriam Steinberg Center for Theatre for a run through Jan. 29, 2006.

Mr. Marmalade follows the lives of two very smart children (as played by adults) who deal with adult issues. Neglected four-year-old Lucy, armed with "a precocious vocabulary" and "killer skills in the kitchen," creates an imaginary world where the titular busy businessman continually promises to spend more time with her.

Starring as the title character, Hall leads a cast that includes Michael Chernus (A Number, Finer Noble Gases), David Costabile (Caroline or Change, Titanic), newcomer Mamie Gummer (upcoming "Hoax" film), Pablo Schreiber (Manuscript, Sin) and Virginia Louise Smith (The Pillowman, Twentieth Century).

Tickets for Mr. Marmalade at the Laura Pels Theatre, located at 111 West 46th Street are available by calling Roundabout Ticket Services at (212) 719-1300. For more information, go online to www.roundabouttheatre.org.
