Naomi Klein and Avi Lewis on adapting This Changes Everything

Canadian author and social activist Naomi Klein and her filmmaker husband Avi Lewis are adapting Klein's best-selling book This Changes Everything into a documentary. 

In their first ever joint interview about the project, they join guest Gill Deacon to explore the connections between climate change and capitalism, the challenges of turning a 500-page book into a two hour movie, and why they remain hopeful in the face of overwhelming environmental challenges.
