I think the intent of this thread was to explore how the plot elements that were added to the film went counter to ideas or themes of the book. That implies that discussion of the book contents vis á vis the movie is legitimate here.
But even leaving the book contents aside: based on the dialogue in the movie, there was no indication that Caspian IX even knew about a green mist. How the seven swords related to anyone or anything Telmarine is never explained - simply that the Lords had them somehow, for some reason. (That itself defies logic: special, magical swords might be present, but would not be carried about for common use.) Even in the movie, the Lords fled to the Lone Islands to escape persecution by Miraz, not to do anything about the green mist. A comment by Lord Bern indicates that they learned of the mist in the Lone Islands, and six of them went out to fight it (why Lord Bern didn't isn't explained, to my memory.)
It seems to me that BK's point in all this is that the introduction of these alien elements not only destroys the harmony of the original story, but creates plot weaknesses that didn't exist in the book. I'm just agreeing with him.
