In The Wake of the Flood, a feature documentary on Canadian author Margaret Atwood's unusual book tour for her novel The Year of the Flood, will premiere in Australia this August.

The film by Toronto director Ron Mann will screen Aug. 4 at the Possible Worlds Festival, an annual festival of Canadian film in Sydney.

Mann brought his documentary Know Your Mushrooms to Possible Worlds in 2009.

Atwood will participate in a live video conversation from Toronto after the screening in Sydney.

In the Wake of the Flood follows Atwood's carbon-neutral book tour, which involved local groups and choirs acting out parts of her narrative in churches and community halls. Each reading Atwood gave on the tour was a fundraiser for a green charity.

The novel examines a period after a global contagion that wipes out most of humanity, and the history of a religious sect called God's Gardeners who believe in living with minimal impact on the environment.

The Canadian novelist and poet is also author of The Handmaid's Tale, Cat's Eye, Alias Grace and The Blind Assassin.

Possible Worlds will release a full lineup of 20 Canadian films on July 1. The festival, in its fifth year, has previously screened Canadian movies such as One Week, Waterlife, Adoration, The Necessities of Life, Passchendaele, Fierce Light, L'Age des Ténèbres and Shake Hands with the Devil.
