'Harry Potter Wizards Collection': JK Rowling Discusses Whether Harry Potter Was Mad (EXCLUSIVE VIDEO)

Hogwarts may have closed its doors forever and Harry, Ron and Hermione may no longer be making magic, but that doesn't mean you can't carry on watching Harry Potter films.

To celebrate the launch of Harry Potter Wizards Collection, the most comprehensive Harry Potter box set ever, The Huffington Post UK has an exclusive behind the scenes clip from the collection.

In the video above, Potter screenwriter Steve Kloves and J.K. Rowling discuss the rumours that boy wizard Harry's world was make-believe, and that he went mad after living with his aunt and uncle.

Kloves tells Rowling: "You made it pretty clear that he was an abused boy."

Just imagine if none of it was real - no Dumbledore, no Professor Snape, no Hedwig and even no Dobby. Surely it can't be true?

The new collection contains 31 discs, including all the films and more than 5 hours of never-before-seen special features. It's released on 10 September and is available to pre-order here.
