Corrected entry: In the scene where Jem is in the bed and the doctor is checking his arm, after his encounter with Bob Ewell, Calpurnia is holding the door shut. When Scout is in the room she spots Boo hiding behind the door. Calpurnia and the doctor should have seen Boo when the door was being held shut.
Corrected entry: When Scout is playing in the tyre, Jem roles it down the street. You see Scout hit the porch steps at the front of the Radley house, but when Jem goes to pick her up, you see him pick her up from the side of the house and not the front.
Corrected entry: When Atticus is in the courtroom, he asks Mr. Ewell to write his name. Two mistakes here: Mr. Ewell wasn't writing letters, just a bunch of random scribbles. But the second is, he's not writing at all. You can see the pencil is about half an inch from the paper.
Corrected entry: If Tom Robinson had a problem with the strength of his left arm, he certainly had enough power and strength to strangle Ms. Mayella.
Corrected entry: When the children and Atticus see the mad dog running up the street, throughout the scene there are shots looking down the street towards the dog. During these shots, you can see what looks like a mountain in the background. The story takes place in Alabama, but there are no mountains in Alabama.
Corrected entry: When Jem and Scout are talking to each other from their beds at night, Jem tells Scout that he was six when their mother died and she was two. That was four years ago which would make Jem ten years old now. After Mr. Ewell is killed and Atticus suspects Jem killed him, he tells the sheriff that he can't remember if Jem is twelve or thirteen.
