The talk about the Joker in the Dark Knight got me to thinking about the most effective villains in movies ... the characters that were purely awful and needed to be exterminated. I'm not talking about misunderstood characters who may have had a good side, but effective villains who stirred all sorts of stuff inside of you. You wanted them dead. A few come to mind: -- The British officer in The Patriot who was Mel Gibson's and Heath Ledger's nemesis. -- Two in the Green Mile: Percy Wetmore and Wild Bill. -- Bruce Dern's character in John Wayne's film, The Cowboys. -- Blue Duck in Lonesome Dove. I'm sure there are many more.
