Continuity mistake: When Father Jud spots (what he thinks is) the discrepancy in the picture Blanc is looking at, you can see in the wider angle that on the counter there's no plastic bag (it is actually behind it) nor paper towel used as a coaster. When he gets closer to the doctor bag and when Dr. Nat Sharp waddles towards the bar, both items are on it. (00:49:00)
Continuity mistake: Inside the "Diavolo" pub, Blanc is checking something out using the picture as a reference. In the POV shot, he's holding the frame, bending his pinky finger, but in the opposite camera angle, he's holding the four fingers straight. (00:48:45)
Continuity mistake: At the morgue, Geraldine and Blanc react to Father Jud saying he shouldn't be there, turning towards him in two different ways with different timing in the two separate shots. (00:45:40)
Continuity mistake: When the doctor pulls the blade out of the body, Jeremy Renner grips the devil head in a different way between shots. (00:35:50)
Continuity mistake: During Martha's first flashback about Grace, the debris in front of the 'harlot' changes between shots when she attacks the kid. (00:14:00)
Continuity mistake: When Samson is cleaning up the exterior of the crypt, he puts the paint roller against the half-deleted 'tank' of the 'rocket ship' in a slightly different spot between shots. The natural light of the scene also changes between shots, as you can easily tell from the shadows cast. It's not an expressive choice, unlike many of the sudden light changes that happen in the movie. (00:09:00)
Continuity mistake: After we see Jud speaking for the first time with the groundskeeper as they drink Pepsi and watch the game, we get to see Jud and Martha working together in the office. The two opening shots are meant to be consecutive, but Martha is holding the paper just in a superficially similar way; her hand is on the corner in the wider angle but a couple of inches higher in the other angle. (00:08:40)
Continuity mistake: Jud asks Martha about the 'harlot w...' he keeps hearing mentioned. She begins talking about Prentice's past and mentions he was widowed, with a daughter. She puts an envelope down on the desk, and the envelope is in a different spot in the next shot. (00:10:15)
Continuity mistake: When Jud gives in and shakes Monsignor Wicks' hand after the painstaking detailing of his self-pleasuring ways, Josh O'Connor's left hand is turned differently in his lap between shot and reverse. (00:07:35)
Continuity mistake: The first time Father Jud meets Martha, she is holding a goblet. Notice the grip she has on it. She walks away from him, and she is holding the item in a different way. (00:05:05)
