The film, made by Denmark's Nordisk Film, documents the architect's life and work, including during the period after his dramatic departure from Australia in 1966, following a dispute with the NSW government, which had stopped paying him.

When Ms Herron welcomed representatives from the NSW government who were in the audience, the crowd broke into laughter.

Last week, Premier Gladys Berejiklian ordered Ms Herron to go ahead with The Everest promotion, overruling her and the 2012 policy governing the World Heritage-listed building.

Although the 2GB shock jock defended his actions last Monday, by Tuesday he had apologised to Ms Herron.

Last Tuesday, more than 1000 demonstrators gathered at the Opera House to protest at the Racing NSW projections on the building.

Ms Herron said later on Sunday night, she had been "overwhelmed" by the crowd reaction and the support she and the Opera House had received last week.

The documentary, which will be rescreened on Tuesday for Opera House staff and those who helped construct the building, shows previously unseen 35mm footage that Utzon had organised to be shot from a camera on top of the Sydney Harbour Bridge showing the construction of the sails over the years he worked on it.

The film also includes the first legally obtained drone images of the building.

Lin Utzon, the architect's daughter told the audience she felt a "deep gratitude" to the way "the Australian people helped finish the story" [of the Sydney Opera House] by "trying to make peace" with the architect in his later years by inviting him to become involved again in the design work.
