Movie: How the Grinch Stole Christmas (1966)
Villain: The Grinch
Played by: Boris Karloff
This list boasts some of the worst villains ever to hit the big screen, from greedy bankers and international super criminals. Most of them committed dastardly deeds on Christmas, they didn't to anything to Christmas. Only the green man had the cojones to launch a full-scale assault the holiday itself. In 26 minutes, the Grinch commits more acts against the yuletide spirit than most devious villains can muster in entire full-length films.
He eventually learns his lesson, but that doesn't take away from how much of a badass he was before his heart grew multiple sizes. The Grinch and his tiny-ass heart set the standard for holiday villainy that still remains unmatched to this day, and he did it all by rhyming, which should definitely earn him some villainous bonus points.
