Factual error: When Harry is confronting the bank robber and the robber says he has to know if Harry had any shots left, Harry cocks the hammer which rotates the cylinder. If you watch closely when he pulls the trigger the cylinder rotates again. This can happen only when the trigger is pulled in double action mode (hammer down). (00:14:00)
Dirty Harry (1971)
1 factual error
Directed by: Don Siegel
Starring: Clint Eastwood, John Vernon, Andrew Robinson, Reni Santoni
Continuity mistake: During the scene on the football pitch where Callahan is torturing Scorpio to force him to say where the kidnapped girl is, there are several shots as if from Callahan's viewpoint. As the camera switches between the two characters, the white painted lines on the pitch mysteriously move or even vanish underneath Scorpio. (01:06:50)
Harry Callahan: What are you going to do with those?
Doctor: Going to cut your pants off.
Harry Callahan: No. I'll take them off.
Doctor: It'll hurt.
Harry Callahan: $29.50, let it hurt.
Trivia: In real-life, Andy Robinson (Scorpio) is a pacifist who dislikes guns. Every time he fired a gun during the early stages of principal photography, he would flinch violently, so director Don Siegel was forced to close down production for a time and send Robinson to a school where he would learn to fire a gun convincingly. In spite of this, he still blinks when he shoots.
Question: Is Callahan holding the binoculars upside down when he is peering down on the apartments looking for Scorpio? He is on the rooftop with the Jesus Saves Sign. They look upside down to me. (00:38:39)
Answer: Yes the binoculars are upside down.
