Opening night is Nov. 11. Performances will now play to Jan. 2, 2011. The original closing date was Dec. 5. The newly constructed Sondheim (formerly Henry Miller's Theatre) is at 124 W. 43rd Street.

"The reaction to Pee-wee's upcoming Broadway engagement has been overwhelming, both in terms of ticket sales and generating excitement, so much so, we needed to add four more weeks of performances," Sanders said in a statement. "The Pee-wee Herman Show is perfect entertainment for family members of all ages and I can't think of a better place to spend the holidays than with Pee-wee's Playhouse."

The stage show is based on Reubens' 1981 cult classic stage production, The Pee-wee Herman Show, with new elements from the ground-breaking CBS show "Pee-wee's Playhouse." It's written by Paul Reubens and Bill Steinkellner, with additional material by John Paragon, with direction by Alex Timbers (Bloody, Bloody Andrew Jackson).

The Pee-wee Herman Show will feature music by Jay Cotton and the work of renowned puppetry artist Basil Twist. The production comes to New York direct from its sold-out run in Los Angeles.

The show, according to the producers, "Reunites the one-and-only Pee-wee Herman (Paul Reubens) with many of the original Playhouse cast of characters — including Miss Yvonne, Cowboy Curtis, Pterri the Pterodactyl, Jambi the Genie, and Chairry — for an all new celebration of sophisticated silliness. An eye-popping 90 minutes of subversive humor and childlike wonder, The Pee-wee Herman Show charts a day in the life of our bow-tied hero, one of the most inspired comic personas of our time." The design team for The Pee-wee Herman Show includes David Korins (scenic design), Ann Closs-Farley (costume design), Jeff Croiter (lighting design), M.L. Dogg (sound design) and Jake Pinholster (projection design).

The complete cast for The Pee-wee Herman Show will be announced shortly.
