It’s March, which means it’s time for our March Mad Movie Madness tournament. This is a super-ambitious project lasting for a (a little over) a month that, when completed, will determine the most popular of our canonical weird movies, and effectively rank the others from 2 to 366.

We’ve actually already seeded every movie from 1-366, using a formula based on IMDb rating, number of IMDb votes (to adjust for obscurity), and page hits on each movie on this site. But the first step in the tournament is to cut the massive field of 366 down to a slightly less massive field of 256. To do that, we’ve taken the lowest seeded teams—220 of them—and placed them into 22 groups of 10 movies each. Your mission, should you choose to accept it, is to vote for up to 5 movies in each group to advance to the next round. When done, this will eliminate the bottom 110 weird movies from the competition.

The play-in round of the tournament will last until March 6th at midnight EST. March 7th is reserved for tiebreakers, if needed. God willing, the official tournament bracket will be released the next day.

So get to voting. If your favorite movie is eliminated in the play-in round, you’ll have no one else to blame. You may vote once every 24 hours.
