The rumor mill has in the past stated that del Toro was in the running for the third film in the franchise, Harry Potter and the Prisoner of Azkaban.
The Annecy Festival is the first time that Guillermo del Toro has spoken publicly about being offered one of the major Harry Potter flicks, and while he didn’t elaborate on which movie it was that he was offered.
With Guillermo del Toro in charge, the horror aspects in that particular book would have likely been amplified on the big screen, but it wasn’t to be.
Del Toro’s pal Alfonso Cuaron eventually took the reins on the film.
