John's Not Mad

John's Not Mad was a QED documentary made by the BBC in 1989. It was ranked, in a British public poll, as one of 50 Greatest Documentaries.

The film shadowed John Davidson, a fifteen year old from Galashiels in Scotland, who had severe Tourette syndrome. John's life was explored in terms of his family and the close-knit community around him, and how they all coped with a misunderstood condition. Oliver Sacks, a neurologist, offers observations on aspects of John's behaviour.

The documentary achieved a cult status soon after it was first aired and, contrary to the "possible good intentions of the film crew, it has been seen as some sort of comedy classic".

John's Not Mad has been released on DVD including footage from John in the 2002 The Boy Can't Help It. John is also featured with Keith Allen in a Channel 4 documentary entitled Tourette De France where he travelled with Keith and a group of Scottish persons with Tourette syndrome to Paris to visit the hospital where Georges Gilles de la Tourette practised.
