You also have said if a movie is canon and its novelization is canon (or vice versa), and dialogue in one is not the same as the other, then which one ought to be canon? So I want to know which one you would consider canon and why, or whether it matters to you and why not if it doesn’t.
I think someone in another thread said that those in charge said that where the book and movie differ, the movie takes precedence.
I would think the original work takes precedence. That is, the Star Wars movies trump the books; but the Harry Potter books trump the movies.
makes sense.
