Mike Nichols ("The Graduate," "Angels in America") directed and Casey Nicholaw (The Drowsy Chaperone) choreographed the show inspired by the 1975 feature film comedy "Monty Python and the Holy Grail," which landed at Broadway's Shubert Theatre for a St. Valentine's Day (Feb. 14, 2005) start and a St. Patrick's Day (March 17) opening.

Spamalot tells the tale of King Arthur and his Knights of the Round Table on their quest from God for the Holy Grail - with a short stop in the dazzling Spam-filled land of Camelot.

The musical features a book by Eric Idle based on the screenplay he co-wrote with Monty Python creators Graham Chapman, John Cleese, Terry Gilliam, Terry Jones and Michael Palin. The new score — with music and lyrics by Idle and composer John Du Prez ("A Fish Called Wanda") — includes songs ("Brave Sir Robin" and "Knights of the Round Table") from the original film as well as Python signature "Always Look on the Bright Side of Life." Spamalot took home prizes at the 2005 Tony Awards for Best Musical, Best Direction (Nichols) and Featured Actress (Sara Ramirez).
