Sir Tom the Dragon Knight
Dragon Lord
Ah, okay. As I often say, there ARE some book-to-movie changes which DO NOT ruin the story. Tolkien does appear to have been a bit of a misogynist; so, as he looks down from Heaven where all faults are cleansed away, he surely won't be upset now at some FEMALE characters being added to his perniciously all-male story.
Yeah I figure it will be fine, as long as they keep in the spirit of the books. You know, without adding immoral themes or something.
