After (re)watching Legend, I have been unfair to it - although the fairies go from seelie to just-good-guys which is a bit crap. Personally I can't wait for Stardust, which, if it is at all true to the book, will teach us all about fairyland.
Meanwhile, I note that Legend includes a character called Princess Lily, and The Princess Bride has a character called Princess Buttercup. Sadly Willow, in Willow, is not a Princess although there are indeed princesses in the film. Did someone notice this when bundling 3 80's Fantasy films together or is it just serendipity?
