Harry Potter author J.K. Rowling told a Carnegie Hall audience in 2007 that she thought of Prof. Dumbledore as gay and that she intended the character of Gellert Grindelwald in Harry Potter and the Deathly Hallows to be Dumbledore's lover, though she did not specify that in the book.
But it looks like the film version (or versions, as the book is split into two movies) will address the author's revelation, and actor Jamie Campbell Bower—who plays Grindelwald in the two Deathly Hallows films—refers to his character the same way Rowling did.
"He's an old friend of Dumbledore's, possible lover," Bower told a group of reporters last Friday in Beverly Hills, Calif., where he was promoting The Twilight Saga: New Moon. (Spoilers ahead for those who haven't read the books!)
Grindelwald, who was killed by Voldemort before the events of Deathly Hallows, appears in the book as a vision; the films require Bower's services for approximately two weeks total. That's a small part of a film shoot that lasts more than a year but should amount to a few significant minutes of screen time between two films.
"At the moment, I've only worked on it for about a week," Bower said. "So I think I've got another week and a bit to go. They're still cracking on with both of them simultaneously, because they've obviously got such a tight schedule they have to do both side by side."
Bower was also committed to playing the Volturi vampire Caius in New Moon. The Potter filmmakers had no problem working Bower's schedule into their production. "It's a machine, Potter," he said. "You go in, you do your thing, and then you go on, whereas with this, it's a lot more finding out about everything and a lot more exploration to do in general."
Harry Potter and the Deathly Hallows: Part I opens Nov. 19, 2010. Part II is due July 15, 2011.
