This is a really interesting article, the author's impressions of the movie-making process. There is a bit about Nic, not much, and some interesting musings about fame and how it affects your life. I enjoyed it.

'I was pleased, too, by Nicholas Cage, mainly because he very quickly became Captain Corelli for me, even though I had originally envisaged the character as being much shorter and altogether different in manner. There was no opportunity to get to know him personally, but then I doubt whether any outsider ever gets to know any megastars personally. They are necessarily surrounded by personnel whose job it is to keep them insulated from all the people who would otherwise become a relentless nuisance, which has the incidental effect of simultaneously shielding them from everyone that they actually would like.

As a mere writer I have had only a few indications of the harassment that the famous can experience, and the strange way in which fame makes it difficult to relate to anyone in a normal fashion, but it has been enough to persuade me that I would, again, rather be boiled in oil, or indeed go back to being a schoolteacher, than be a megastar like Nicholas Cage. In the few scenes that I watched, he got it all just right, and I take my hat off to him.'
