LONDON (Reuters) - As the studio behind the Harry Potter films likes to remind us, It all ends here. Harry Potter and the Deathly Hallows - Part 2, the eighth and final installment in one of cinemas most successful series, has its premiere in London in a week, and experts predict records could tumble when it hits theatres on July 15. Its premiere is on July 7 in London, and fans of the franchise can check out the action on the red carpet live on YouTube. The event will go down on YouTubes Harry Potter channel from 8 to 11 p.m. PT and will feature the cast of the film as well as author JK Rowling. In preparation, YouTube has packed the Potter channel with all seven films (which one can rent), behind-the-scenes footage, parodies and interviews. The cast and crew have promised the most explosive Potter movie yet, even though computer-generated special effects and action scenes have been predominant throughout. The last movie is going to be really, really fast-paced and a load of action in it and it is like a war film, Harry Potter actor Daniel Radcliffe told Reuters in a recent interview. The final film, the first Potter installment to be available in 3D, will reveal whether boy wizard Potter prevails over his evil nemesis Lord Voldemort in a classic good-versus-evil climax, although JK Rowlings novels provide the answer.
