Previously, Harry Potter filmmakers were reluctant to give away too many of the movies’ behind-the-scenes secrets, fearing it would destroy the series’ key magic themes. But with Blu-ray offering a wealth of creative opportunity, Half-Blood Prince was prepared brimming with extra content.

Besides detailing Half-Blood Prince, Yates and others also offered some surprising sneak peeks to the final two theatrical installments of the Harry Potter franchise, slated for 2010 and 2011 release. At certain points, Radcliffe will appear naked.

In one scene, “a horcrux [carrying a piece of Voldemort’s soul] defends itself by producing nightmarish visions, and one shows Hermione and Harry embracing and kissing,” explained Yates. “It’s something intriguing and sensual for Rupert to react to, and Dan will be bare for that.”
