Lynch, while talking about the genesis of his film Erazor Head, says that he himself could not understand what the film was about for a very long time. He was desperately looking for some key that would allow him to logically combine all the material that had already been shot. At some point of this process, he was reading the Bible and came across a sentence that would fit the lock. In a moment that he describes as enlightenment he suddenly realised what exactly the film he was making was about. What was the sentence? I have never revealed this to anyone, says Lynch, and I don’t think I will ever do so.
