On Friday, Jennifer Baichwal and Ed Burtynsky's new film Watermark will be released in Toronto at the TIFF Lightbox and Varsity Cinemas before it pops up all across North America on October 11th.As a topically unrelated follow-up to the pair's widely celebrated documentary about factories and landfills, Manufactured Landscapes, Watermark explores the planet's relationship with water. To make this incredibly epic documentary, Jennifer, her husband and cinematographer Nick Pencier, and Ed traveled to ten different countries. They did everything from visit the construction site of a Chinese dam set to be eight times the size of the Hoover Dam, and they checked out a mind-bogglingly large religious ceremony by the water in India.Since we think the film sounds like one of the coolest and most difficult-to-produce documentaries that's been released in quite a while, we went out to speak with Jennifer, Nick, and Ed on the Georgian Bay in Ontario to discuss Watermark, water itself, and how their own understanding of water changed while making this film.Enjoy.
