A new trailer for Harry Potter and the Half-Blood Prince has been released.

The trailer - featuring all-new footage of the sixth film in the Potter franchise - debuts months ahead of the film's July 2009 release.

Directed by David Yates, the latest Potter film follows the trials of Harry as he embarks on his sixth year at Hogwarts School of Witchcraft and Wizardry.

The film also lays the foundation for Potter's final battle against Voldemort as told in the final book, Harry Potter and the Deathly Hallows.
