Anachronisms: In the final scene when Pip is persuading Estella to leave Satis House with him, a 'Chad' is clearly visible drawn on the screen behind him (Chads were a popular form of graffiti in the 1940s - a character with a big nose looking over a wall)
Revealing mistakes: As Joe says goodbye to Pip after dinner with Herbert, Joe's fake eyebrows are loose.
Continuity: After Uncle Pumblechook parks his carriage in front of the gate at Satis House and drops off the young Pip, Estella leads Pip away from the gate. First, the carriage is clearly seen parked outside the gate. In a later shot, as Pip is walking, the carriage is gone, and in a subsequent shot, the carriage is back in view outside the gate again.
Continuity: When Joe drops his hat into a saucer during his visit with Pip and Herbert Pocket, the hat is crushed slightly and leaning towards Pip. In the next shot, the hat is in its original condition and is leaning towards Herbert.
Revealing mistakes: Early in the movie, when Mrs. Joe is beating the young Pip, she is clearly not touching him, just swinging the switch up and down behind him.
Boom mic visible: After leaving the office of Jaggers, Pip and Mr. Wemmick are walking down the street and when they approach the corner the conversation turns to a discussion of Jaggers' servant Molly; at this point the shadow of the boom mic is visible on the wall behind them in the left side of the shot.
