I'm interested to hear about other people's favourite nature-based films and documentaries (going along with the "Celebrate Biodiversity" theme). One I'm looking forward to is A Birder's Guide to Everything. I really liked The Big Year (despite poor reviews on some sites).
Anne, there is a page on the web site "Screenings and Tickets" -- it is only going to be playing in large urban centres early on as it does the festival circuit/indie theatres. Whether it hits the mainstream, I suppose, depends on its success.
