To celebrate the upcoming release of 'Harry Potter and the Deathly Hallows: Part 1,' Moviefone is hosting a search to find the biggest 'Harry Potter' fan in America.

So if you've read every 'Harry Potter' book, seen every movie and think you know everything there is to know about them, we want you to enter! This is your chance to show your unique devotion to this worldwide phenomenon and finally get recognized for it. Come on, show us your crazy memorabilia, your homemade 'Harry Potter' pillows, the cat you named after Hermione, your tattoos.

If you think you fit the bill, submit a short video (no longer than three minutes) below, telling us why you think you deserve to be named the biggest Potterhead.

Once you've uploaded your video, fellow fans and supporters can vote you up or down. Then, on Mon., Nov. 22, the entry with the most "up" votes will be crowned America's number-one 'Harry Potter' fan. The winner will receive the t-shirt of his or her choice from Busted Tees and additional prizes to be determined. (Plus bragging rights, of course!)

While you're at it, head on over to our Facebook page and "like" us for all the latest Harry Potter updates.

IMPORTANT NOTE: When you sign up and submit your video, make sure you do so by using one of the following email accounts: Gmail, Yahoo! or AOL. Do NOT use a social network to login and create an account. We need your email address in order to contact you, should you win.
