Shot in very rugged terrain in the remote Cardamom mountain region of Cambodia. To provide lighting for remote night scenes in the forest, generators - small enough to be strapped to the back of a motorcycle - were used to power daylight-balanced lights.
At the end of 'Have Forest, Have Life', the giant snake which is released back into the wild is actually two giant snakes - both were released at the same point in the river, but covered from different angles and edited together to enhance coverage and production values.
