The Dream of Perfection is as extraordinary as its provocative subject matter, the dramatic story of the building of the Sydney Opera House, culminating in Utzon’s departure from the project. Director John Weiley was commissioned in 1968 to make the documentary Autopsy on a Dream by then BBC2 controller David Attenborough, and following its only screening on the BBC, it was destroyed – literally chopped to pieces on the chopping block. Miraculously, a mute print of Autopsy on a Dream was rediscovered in a BBC vault this year, and has now been restored with sound saved by John Weiley, and with a new prologue.
