On 20 October 1973, the Sydney Opera House was officially opened by Queen Elizabeth II. From conception to completion, it had taken more than 15 years and over $100 million dollars. In the years since its completion, the Sydney Opera House has become one of the most identifiable of Australia’s icons - ranking with the Sydney Harbour Bridge, Uluru, the koala and kangaroo - and is considered by many to be among the world's great architectural masterpieces.

In 1968, John Weiley shot 'Autopsy on a Dream' - a film about the Sydney Opera House detailing its construction process and the politics of Jorn Utzon's dismissal. Weiley's film was controversial; it was screened once and then he was told it had been destroyed. Forty five years later a copy was discovered in the BBC vaults by an ABC producer looking for archive footage of the Opera House. Weiley was contacted and told about a film that had no sound track. Weiley was overjoyed; for years he had kept the original sound. So began the painstaking process of restoring this record of a unique moment in Australian culture to its former glory, complete with updated voice-over from the original narrator, Bob Ellis. It is set in context by a 30 minute prologue entitled 'The Dream of Perfection'. Made by the same filmmaker, John Weiley, forty-five years on, 'Dream of Perfection' tells the story of the 1968 film - from commission to destruction, to surprise resurrection.
