Andrew Robinson did such a superb acting job in that movie that he basically typecast himself out of any other roles for years. I remember reading an interview where he said that people used to cross the street when they would see him walking towards them!
Andy Robinson, who played the psycho killer in the first Dirty Harry said the role severely typecast him and virtually shot down his acting career. He played his role so well he was always asked to be a psycho killer. He did have a co-starring role as Walter Matthau’s criminal sidekick in “Charlie Varrick.”
Great movie! One of my favorite Dirty Harry movies. The guy was a total creepazoid.
