Monty Python's 'Spamalot' To End Its Successful Broadway Run

After a nearly four-year run on Broadway, Monty Python’s “Spamalot” will perform its final show on January 18 at its home the Shubert Theatre, according to The New York Times. The Tony Award-winning spectacle, based on the 1975 movie "Monty Python and the Holy Grail," is the latest casualty on Broadway, following in the wake of "Hairspray" and "Legally Blonde."

Currently, the show stars "American Idol" alum and new dad Clay Aiken, who will end his role as Sir Robin on January 4. Other castmembers include Michael Siberry, Merle Dandridge, Tom Deckman, Rick Holmes, Bradley Dean, Wally Dunn and David Hibbard. In the past, Tim Curry, Hank Azaria, Sara Ramirez of "Grey's Anatomy" and Monty Python's own John Cleese have all starred in the show.

The show opened in March 2005, with director Mike Nichols and lyricist (and Monty Python member) Eric Idle at the helm, and defied expectations by making back its investment within the first six months of opening. It is expected to gross $175 million in revenue by the time it closes, a spokesman told the Times. The show is still touring the country and its run in London's West End ends January 3.

The Times also reports that Broadway's troubles may stem from weak ticket sales as a result of the struggling economy. This is the time of year when many people buy tickets for the holiday season — but, despite still selling tickets, "Spamalot" has recently failed to break even.
