OK, so although people don’t typically think about fanfiction when they hear Wicked, this movie actually counts as being based on fanfiction as well (depending on how you define fanfiction, but hey, let’s not be restrictive here).
The Wicked musical is based on the 1995 book, Wicked: The Life and Times of the Wicked Witch of the West by Gregory Maguire — and this book, of course, takes characters and stories from the original L Frank Baum story, The Wonderful Wizard of Oz. So, I don’t know about you, but that’s fanfiction to me. This movie hasn’t hit the theatres quite yet, but you best believe I’ll be there when it does.
