Welcome to our version of the NCAA basketball tournament where 64 of the most terrifying monsters in horror film history will battle for the top spot.

All you have to do is follow me on Twitter (@tobiamd) or the hashtags #MarchtoMadness and #March2Madness to vote the winner of each day’s head-to-head match-up.

Each day of an NCAA tourney game, our sinister match-ups will be posted on Twitter. Simply cast your vote based on whatever criteria you choose who’s the strongest, scariest movie, etc. Be sure to click on the information link next to each monster for a quick sketch of their background (and how they relate to psychiatry).

May the best monster win.
