Re: His dark materials movie
If whoever is writing the script goes and starts to use material from the other books, then the film will be nowhere near as good as it could be. I don't care if the scriptwriter is some unknown, or Philip Pullman - there's no point in changing things for the first film, because by the time the third film is being written, things will have changed so dramatically that it won't be His Dark Materials any more.
I agree with you on SoUE - again, they brought things in from other books, mashed them together, and produced something awful.
And the same happened with the Alex Rider film - Sabine Pleasure? In Stormbreaker?!
