23 Gollum, The Lord of The Rings Trilogy (2001–03)
Forget Sauron, that giant spider and those butch-beastly Orcs; the most memorable (and ickiest) bad guy in Tolkien’s epic saga is the feral, fallen creature willing to do anything to possess his preciousss. Credit Andy Serkis for adding a sympathetic element to this tortured soul, turning this cursed character into a truly tragic figure.
