I was thinking about the legacy of ghosts in fiction, and specifically the moral power of those Dickensian ghosts. Because a ghost can be a very powerful but also manipulative element.
I know that I shall have lost to the jungle if I take a weak moral standpoint or relax my mental punctiliousness. I have therefore come to a certain belief which is based on three powerful effective commandments: THOU SHALT BE ENTERTAINING AT ALL TIMES. THOU SHALT OBEY THY ARTISTIC CONSCIENCE AT ALL TIMES. THOU SHALT MAKE EACH FILM AS IF IT WERE THY LAST.
