Two basic questions seem to emerge. I would add a further refinement to how we need to ask the first question though. I don't think that those things are able to be translated to film, quite honestly. As I pointed in another post, there are few words in Tolkien's published fiction which have words which are Latinate or Old French in origin. He avoids them whenever and whereever possible.
Dragons have hoards, that word is used far more often than treasure, for example.
