Stay Another Day East 17
With the one year countdown to the Olympics next week this weekend sees events across London.
It's a chance for organisers to show off the art, culture and sport the UK has to offer.
As part of the Cultural Olympiad as it's know, in Trafalagar Square there's the premiere of children's movie The Itch Of The Golden Nit.
It stars the voices of David Walliams and Catherine Tate.
There is also a floating cinema and treasure hunt around the Olympic Park.
