The veteran singers claim Warner Bros. has trampled on their long and hard-fought reputation by using their copyrighted name for a band in the upcoming "Harry Potter" blockbuster, the Toronto Globe and Mail reported Tuesday.
The suit demands either Warner Bros. change the name of the group in the movie or help them establish a new identity, the newspaper said.
The attorney for the 15-year-old band of members in their 50's says the two sides are talking, but if a settlement is not reached, they will move for an emergency injunction to bar the November release of "Harry Potter and Goblet of Fire" in Canada.
The movie reportedly has a group called The Wyrd Sisters playing at the Hogwart's Ball, the Globe & Mail said. In J.K. Rowling's book, the band was called the Weird Sisters.
The movie band, by the way, features an all-star British lineup including Jarvis Cocker of Pulp and Radiohead's Johnny Greenwood and Phil Selway.
