When he was the director, Guillermo spoke extensively on how he planned to handle Smaug. Some of his most in-depth comments were made right here on TORn: “Smaug should not be “the Dragon in the Hobbit movie” as if it was just “another” creature in a Bestiary. Smaug should be “The DRAGON” for all movies past and present. The shadow he cast and the greed he comes to embody- the “need to own” casts its long shadow and creates a thematic / dramatic continuity of sorts that articulates the story throughout.” It remains to be seen how much of the original, Del Toro influenced Smaug will make it into the movies.
