To celebrate the 40th Anniversary of its release, Monty Python and the Holy Grail is returning to 500 UK cinemas for one night only. Taking place on October 14, 2015 and will be accompanied by a specially filmed, exclusive introduction from Terry Jones, Terry Gilliam, Michael Palin, Eric Idle and John Cleese.

The classic comedy will also be presented in an all new sing-a-long version for the very first time, although that hasn’t stopped us fans singing along to our DVDs for years. Right? So dust off your fancy dress, cut a coconut in half and remember that Brave Sir Robin buggered off because The Holy Grail deserves to be seen on the big screen. A special 40th Anniversary Blu-ray will be out later this year jam packed with brand new featires, but we’ll bring you more details on that closer to its release.

England 932 A.D. and King Arthur accompanied by his trusty servant Patsy is seeking knights to join his Round Table at Camelot.

Having recruited a band of wise, brave, pure and not-quite-so-brave lords, Arthur and his entourage avoid the silliness of Camelot and encounter God in a wondrous vision. He sets the band of heroes on a noble quest: to find the Holy Grail.
