Watching the completed version of The Two Towers for example, I was very conscious of scenes - sometimes whole sequences - that I had seen being filmed or edited but which hadn't made it into the final cut.
Maybe it's just my own chronic morbidity and melancholia, but I really do think about it a great deal and quite often in the small hours of the night when, it is said, the greatest numbers of people die.
The older we get, the swifter time seems to pass and the quicker memories seem to fade.
The biggest challenge was trying to convey the story of the making of a film that isn't finished yet - and which won't be finished until the third film, The Return of the King, reaches our cinemas towards the end of 2003!
