Harry Potter And The Reverse Confusion
Via E Online: Real band WYRD SISTERS prevent fictional band WYRD SISTERS from performing on 'Harry Potter and the Goblet of Fire'soundtrack.
The (real) band's leader articulated the typical 'reverse confusion' concern:
"They are so much more huge than us in their reach that we'll go out on tour a month after the movie comes out--and we'll go all over to Australia, to New Zealand--and people will wonder who are these strange people stealing the Harry Potter name."
Judge Posner suggests that this might be product disparagement, not reverse confusion.
