so, it's fun and all, but i don't understand how it can be considered to be a novelisation of the film itself. i have always wondered why such a thing isn't made from the film. ah, hollywood. as if i can demand it make sense. heh.
I can answer that. Because 99% of the time, the author of the novelization never gets a chance to see the movie. The book has to be on sale when the movie comes out, so it has to be written long before the movie is finished. Most of the time, we're working from an early version of the script plus a handful of still photos and maybe, if we're lucky, some early production sketches.
Basically, it's all about describing a movie you haven't seen yet--which can be just as tricky as it sounds!
I've written six movie novelizations, and edited many more, and I have
never seen more than a few minutes of footage from the movies in the question.
