Pictured: The winners of last year's Halloween Costume Contest: Headless Harry Potter and Iron Man

We host a lot of contests throughout the year, but none of them come close to the awesomeness that is our annual Halloween Costume Contest. This will be our sixth year doing this, and we're looking to make it our biggest and best yet. Once again, we have two fantastic prize packages for the best adult costume and best youth costume, so start brainstorming your fantastic movie-related costumes now because this is one contest you'll definitely want to be a part of.

So, again, that's two prize packages this year: One for adults over 18 and one for kids under 18. Like in previous years (check out last year's winners), your costumes MUST be movie-related. We're taking submissions starting now through November 3rd, giving you a couple days after Halloween to get your freakish photos all together. Once our spook-tacular judges here at Cinematical and Moviefone narrow the field down to 10 finalists in each category, we'll then let you vote (via poll) for the winner. And speaking of winners, head after the jump to see what you'll receive ...
