The amount of things to do on this project is incredible. When I embarked I thought we'd shoot 'making of' stuff all the way, but the reality is that even filming the film is hard enough work - to film the filming of the film would just be too much. I'd like to go back at the end and cover how we do some things - we really learned a lot. The other reason it's hard to do a 'making of' is that I actually don't know how to do this stuff, so we'd waste a lot of time explaining how to do it, only to discover a better way two weeks later.
