Andy Robinson played the psycho killer so well in “Dirty Harry” that he complained that he was typecast and did indeed have a hard time getting acting roles as an ordinary person. He did play Harmon, Walter Matthau’s partner in crime in “Charlie Varrick.” I can’t think of him in another movie, although I’m sure he was in others.
He also played the a-hole police chief in “Cobra” and the military school barber in “Child’s Play 3”.
