A script of the classic movie Life Of Brian is set to go under the hammer.

John Cleese, Terry Jones, Terry Gilliam and Michael Palin have signed the script, which will be auctioned at the Great British Comedy Event.

Mr Gilliam and Mr Palin are attending the do, alongside the likes of Dawn French, Jennifer Saunders, Ian Hislop and Paul Merton. Mr Palin said: "This is one of the most important working scripts of Life Of Brian. It belonged to our heroic, and very funny, first assistant director Jonathan Benson (A Fish Called Wanda, Local Hero) whose job it was to keep cast, crew and John Cleese happy every day of the shoot in Tunisia. Hence the blood sweat and tears in which it is drenched."

He joked: "This is a ridiculously unique souvenir of the film voted Best Comedy Of All Time by the Kyrgyzstan Military Academy."

Attendees will also be able to bid for a chance to sit in the famous Have I Got News For You chair and present a round of the show with Paul Merton and Ian Hislop - which will be filmed for their eyes only.

The event, which will feature performances from the stars, will be hosted by comedian Alexander Armstrong and takes place on June 8 in London to raise cash for the National Film and Television School.

It follows in the footsteps of the Great British Movie Event, which raised more than £400,000 for the school.
