No it's a illustrated relfexion he made about cinema -which was pretty new these days- taken from a letter he wrotte to somebody. He says that maybe he will be making money from cinema someday, therefore he didn't deny writting a script or something like that. He was interested in the way movies were made, as he said, like in any other form of art. Interesting, I think. IMaybe he wouldn't have hated the Milius' movie, after all, differences and alterations apart. But who knows.
