Here's a new image, shot during the week. It seemed like a powerful visual and one that could be used as a standalone picture, almost a poster. But is it too dark and sinister for a children's movie? Maybe. There will be some more variations coming along soon.
P.S. fun fact - shortly after this was taken we got the head stuck up a cliff. You can see how it happened here - http://youtu.be/iG6ESWpplOY
