Continuity: When Bob Ewell is on the witness stand and Atticus asks him if he ran for a doctor, Atticus is hovering over Ewell and his visible shadow behind Ewell reflects this. When the camera shifts to Atticus, he is a good 10-15 feet away. When the camera returns to Ewell, Atticus' shadow is still there.

Revealing: When Atticus kills the mad dog, you can see its hind legs being pulled by someone off screen.

Continuity: When the children go to the courthouse and up to the courtroom door, there are two solid doors with covered panels (that do not let light through), with a clear transom window above the doors. However, when the children boost Dill up to see into the courtroom, the doors' top panels are clear windows.

Continuity: Early in the courtroom scene there is a shot of Gregory Peck that is reversed. The part in his hair is not on the same side of his head that it is in the rest of the film.

Factual error: The time period of the film is 1932. In the opening title sequence, you see someone playing with Crayola Crayons (I assume it's Scout). One of the Crayons is labeled "Melon". Binney & Smith didn't sell the Melon colored crayon until 1949. Crayons produced from 1903 to 1948 sold for a nickel and contained only eight colors: red, orange, yellow, green, blue, violet, brown, and black.

Continuity: When the kids roll the tyre down the street with Scout in it, the tyre is seen heading straight about to crash against a pole. Shot changes and the tyre has magically moved 6 feet to the left and is now heading to the house.

Continuity: After Scout gets out of her ham costume, she runs down the street towards her house and as she runs past the street lamp, someone didn't do a very good job editing the film together.

Continuity: 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.
