If you haven't started thinking about a Halloween costume yet, now is the time to get on it! And if you're looking for a funny or clever idea, you can't beat one of these movie halloween costumes.

There are some classic movie Halloween costumes in this gallery. And while some of the movies might be old (hello 'Office Space' and 'The Hangover'), they are still funny and would still probably win you that contest from your local bar.

A few of the best movie halloween costumes in this gallery would have to be Ghostbusters, Wayne's World, Spaceballs (I used to love that movie), Ace Ventura, Ferris Bueller's Day Off, Up, Fight Club, Austin Powers, and Zoolander.

Given the lack of new pop culture references this year, your best bet might be to go through a list of your favorite movies and try to think of a movie Halloween costume you could wear. And don't be afraid to go back as far as you can! I think costumes like the Clueless and Jay and Silent Bob ones are amazing, even though they are both from the 90's!
