Some horror movies are defined more by the actors who played iconic roles rather than the story or the setting etc. Take Jack Nicholson in The Shining – his legendary portrayal of Jack Torrance. The movie wouldn’t be the same without his acting...
Another perfect example is Anthony Hopkins as Hannibal Lecter in The Silence of the Lambs. His performance is so intense and captivating that it’s impossible to imagine anyone else bringing the same level of terrifying charisma to the role!
