Who doesn't enjoy Harry Potter? It has magic, action, comedy, romance and films whose stars who have played the same parts for a decade. But few can say they love J.K. Rowling's creation as much as this fan, who simply calls himself Harry Potter. In the clip, which was created for a MovieFone contest to find the series' biggest fan, Potter shows off his house full of memorabilia, his encyclopedic knowledge of everything Hogwarts and his tattoo of J.K. Rowling's signature(!). We assume much of it will be incinerated after he sits through Deathly Hallows Part 1.
