Revolution, the number one Canadian documentary so far in 2013, was released on DVD this week. A\J web editor Emily Slofstra had the chance to speak with filmmaker Rob Stewart. While Revolution had some dark moments, Stewart could probably win the award for Most Hopeful Environmentalist, which became evident very early on in the interview. The documentary is full of stunning underwater wildlife cinematography, including some amazing night shots – listen to the podcast to hear about what it’s like in the ocean at night.
