Documentary exploring more than a century of animation in Britain, including the creative and technical inventiveness of the UK's greatest animation pioneers. The defining characteristic of British animation has always been ingenuity. Unable to compete with the big American studios, animators in Britain were forced to experiment, developing their own signature styles. The documentary uncovers the trade secrets of animation legends like Bob Godfrey, John Halas and Joy Batchelor, Len Lye and Bristol's world-renowned Aardman Animations. Tracing the development of British animation from the end of the Victorian era to contemporary blockbusters, Secrets of British Animation shows the perseverance and determination that are part of the animator's mind-set. Focusing on the handmade tradition of animation in the UK, the programme includes newly-remastered early films from the archive of the British Film Institute.
