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.
