The Mary Poppins cast will help kick off the week and participate as contestants on the show, donating their winnings to The Actors Fund, a national human services organization that helps professionals in performing arts and entertainment in times of need, crisis or transition.

Throughout the week on "Millionaire," each contestant will be asked one Broadway-themed question. If they answer correctly, they win tickets to a Broadway show for themselves as well as members of the studio audience.

Mary Poppins cast members will be the first Broadway contestants in "Millionaire" history. The appearance will also celebrate the production's fifth year on Broadway, airing just prior to the show's anniversary, Nov. 16.

The Broadway production of Mary Poppins officially opened at the New Amsterdam Theatre on Nov. 16, 2006, recouping its initial Broadway investment within 52 weeks of its premiere. It is the only show from the 2006-2007 theatrical season still running. Mary Poppins surpassed Pippin to become the 30th longest-running show in Broadway history when it played its 1,945th performance July 16 at 2 PM at the New Amsterdam.

Richard Eyre directs Mary Poppins, which features choreography and co-direction by Matthew Bourne and boasts original songs from the film — with music and lyrics by Richard M. Sherman and Robert B. Sherman — as well as new songs and additional music and lyrics by George Stiles and Anthony Drewe. Julian Fellowes wrote the book.
