Open air premiere for Golden Nit
The Itch Of The Golden Nit will have its public premiere during this year's London 2012 Open Weekend.
The film, made for children by children as part of the Cultural Olympiad build-up to the Games, is voiced by a star cast of British actors including David Walliams, Miranda Hart and Catherine Tate.
It is one of the highlights of the Open Weekend running nationwide from July 22-24 which this year celebrates the one year countdown to the Games.
Big screens will transform London's Trafalgar Square for the public premiere of the film on Saturday July 23.
Thousands of five to 13 year-olds helped create the 30-minute story via 250 workshops or by uploading their drawings to a special website. Aardman Animations, the creators of Wallace & and Gromit, helped bring the story to life as part of the Tate Movie Project.
The hero is 11-year-old Beanie, who is on a mission to return the sun's battery - the Golden Nit.
Over the weekend there will also be chances to try the mascot motion sensor game Swim Wenlock Swim and a special screening of Chariots Of Fire, the Oscar-winning film about British sprinters Eric Liddell and Harold Abrahams at the 1924 Olympics.
