Emma Watson’s curls take on a life of their own in this new still from Harry Potter and the Half-Blood Prince.

In the upcoming fantasy flick, emboldened by the return of Lord Voldemort, the Death Eaters are wreaking havoc in both the Muggle and wizarding worlds and Hogwarts is no longer the safe haven it once was. Harry (Daniel Radcliffe) suspects that new dangers may lie within the castle, but Dumbledore (Michael Gambon) is more intent upon preparing him for the final battle that he knows is fast approaching. He needs Harry to help him uncover a vital key to unlocking Voldemort’s defenses–critical information known only to Hogwarts’ former Potions Professor, Horace Slughorn (Jim Broadbent). With that in mind, Dumbledore manipulates his old colleague into returning to his previous post with promises of more money, a bigger office…and the chance to teach the famous Harry Potter.
