Monty Python musical Spamalot has extended its run at the Playhouse Theatre to 8 February 2014.

Producers have also announced that Monty Python member Michael Palin will appear as one of a number of 'celebrity Gods' on screen during the show to raise money for charity.

Palin steps into the robes previously worn by Hugh Bonneville, Barbara Windsor, Larry Lamb, Bradley Walsh, Simon Callow and Christopher Biggins, who have also filmed the part of God.

According to press material, "They in turn have sent Eric Idle off down the pub throughout the warmer months, as he usually plays the role on screen (and will pop up from time to time when the other Gods are off inventing America)."

The Summer of Spamalot Charity Gods is raising money for several charities including Headley Court Rehabilitation Centre, The Make A Wish Foundation, the Great Ormond Street Hospital, Scene & Heard, Stage For Age and Keats Community Library, which are supported by the actors who are playing God (who each donate their fee for the role).

Michael Palin's performance will be shown from Monday (26 August) until Saturday (31 August). His nominated charity is Action for Stammering Children.

The role of God features in Spamalot when King Arthur and the Knights of The Round Table are given their quest to find The Holy Grail.

Howard Panter, producer of Spamalot for Ambassador Theatre Group, said: "It is a wonderful opportunity to be able to bring friends of the show in to the role of God in this way, so that we can help such deserving causes while making audiences laugh at the same time."

Comedian and actor Les Dennis is currently playing King Arthur, while Bonnie Langford plays The Lady of The Lake. Life's Too Short star Warwick Davis joins the cast as Patsy from 23 September through to 19 October 2013.

Spamalot recently started a new performance schedule, which includes two shows on Fridays at 6pm and 9pm.
