Continuity mistake: As Jake gets chased by the farmers in the orange grove the marks on his windshield change between shots. (01:09:40)
Continuity mistake: As Evelyn Mulwray drives Jake home after his altercation with the farmer, look closely at the piece of paper he pulls out of his pocket with the landowners names on at. It doesn't have any of the paper tabs hanging off of it that we saw before as Jake stole it from the Hall of Records. (01:13:45)
Continuity mistake: Mulwray's Secretary and Jake have a conversation as he waits to talk to Russ Yelburton. They do an excellent job keeping things tidy on her desk between shots but the white flowers and Jake's hat move without anyone going near them. (00:53:15)
Continuity mistake: At Hollis Mulwray's office, Jake looks at the picture of Noah Cross on the wall. At first the shadow of his head falls on the picture but in the next close-up shot it's gone. (00:51:05)
Continuity mistake: Jake and Noah Cross sit down to eat and the piece of lemon on Jake's plate moves between shots in the close-up. (01:01:15)

Continuity mistake: Jake has tea at Evelyn Mulwray's house and she agrees to drop the charges against him. Evelyn is wearing a scarf that she unties but does not take totally off her neck. In the next shot it's off her neck. (00:28:55)
Continuity mistake: Jake walks back into his office after getting a shave at the barber shop and his hair is combed backwards. Later in the scene as he tells the joke about the Chinamen his hair is still parted in the middle but combed sideways to the left and right. (00:18:30)
Continuity mistake: The left side of Barney the barber's bowtie is tied differently between shots as he gives Jake a shave. (00:17:10)
Continuity mistake: As Jake gets a shave in the barber shop we see the picture he took of Katherine Cross and Hollis Mulwray in the newspaper. If you look closely it's obvious that these are not the same actors we saw in the previous scene. (00:16:20)
Continuity mistake: In the barber shop as Jake gets a shave look closely at the shaving cream on his face. In the first shot it reaches all the way up to his lower lip, but when he gets out of the barber's chair to yell at the banker, it's nowhere near his bottom lip. (00:17:05)
Continuity mistake: When we see Katherine Cross and Hollis Mulwray's reflection in Jake's camera lens, Hollis is standing in a different spot than we saw in the shot before. In the reflection he's in front of the chair but in the previous shot he was next to the chair. (00:16:05)

Continuity mistake: After leaving Evelyn Mulwray, Jake goes to the Oak Pass Reservoir to look for Hollis Mulwray. If you look at the design on his tie, it's obvious that it has been re-tied. (00:31:30)
Continuity mistake: When Mayor Bagby speaks at the water and power meeting the map behind him curls up on the left in some shots and not in others. (00:06:00)
