Samara - Bonnie Morgan
Naturally, the makers of The Ring had to find a contortionist to play creepy Samara. At the end of the film, she crawls out from the TV to tell her story, which is still one of the most important scenes in horror cinema. The creepy movements are all real thanks to actor Bonnie Morgan.
Hannibal Lecter - Anthony Hopkins
Anthony Hopkins is one of the most iconic actors of all time. His role as Hannibal Lecter in The Silence of the Lambs is still revered as a classic. Unlike most scary horror villains, he wasn't in a full costume. He was simply himself, dressed up as a prisonor. The muzzle is iconic, of course, but the rest of his terrifying character is just Hopkins himself.
