Payback is a 2012 documentary film from Jennifer Baichwal based on Margaret Atwood's Payback: Debt and the Shadow Side of Wealth, which investigates the concept of debt in societies across the world (and not only on a monetary level). As a Canadian, Baichwal was quite familiar with Atwood's reputation: A number of prominent intellectuals provide commentary, including economist and writer Raj Patel, ecologist William E. Rees, historian of religions Karen Armstrong, and former UN High Commissioner for Human Rights Louise Arbour.
