According to the trailer, its the motion picture event of a generation – a franchise so universally successful that it’s made author JK Rowling one of the richest women in the world. And now, finally, the Harry Potter saga is coming to a close. Ish. Warner Bros have released the first full trailer for Harry Potter and The Deathly Hallows Part 1 – to be released in the UK in November. Part 2 won’t be hitting our screens until next summer, so for all of those who can’t bear to let go of Harry and crew, you’ve got a bit of time yet.
