Michael Gambon as Albus Dumbledore in Harry Potter and the Half-Blood Prince

Warner Brothers has released the full trailer for the upcoming Harry Potter adventure. This is probably to soothe fans that were hoping for a complete film at this time, before the studio had to push the release to next year, because of delays related to the writer’s strike.

After discovering an old book marked mysteriously This book is the property of the Half-Blood Prince, Harry soon begins to learn more about Lord Voldemort’s dark past.

Harry Potter and the Half-Blood Prince is being directed by David Yates, and stars Daniel Radcliffe, Rupert Grint, Emma Watson, Helena Bonham Carter, David Bradley, Robbie Coltrane, Warwick Davis, Tom Felton, Michael Gambon, Alan Rickman, Maggie Smith, Natalia Tena, Julie Walters, David Thewlis, Evanna Lynch, Matthew Lewis, Bonnie Wright, Jim Broadbent, Helen McCrory, Jessie Cave, Hero Fiennes Tiffin and Frank Dillane.
