Continuity mistake: In the shot where Mattie walks towards the toilet at her school, you can see there's a pencil in her hair pointing downwards. When she's inside the toilet, the pencil's direction and her hair have both changed.
Continuity mistake: The scene with Daphne and Velma trying to talk some sense into Carol about the Spencer issue begins with Daphne close to the gap between two tables (look at the shot that precedes the moment when Velma clears her throat), and seemingly no space for anyone to join on Carol's left. When Mikayla joins she finds a lot of space though, and no wonder; from a wider angle it's obvious that now it's an entirely different table. (00:29:20)
Continuity mistake: In the scene where Murdock is in jail talking with Emma on the phones through the glass, he presses his fingers to hers, against the glass, & the glass shatters. Right when it is shattering & he pulls away, if you look very carefully you can see the reflection of his hand in an additional pane of glass that is still there! The next shot shows no glass as they kiss, but when the original glass breaks, there is still a pane of glass remaining, as evidenced by the reflection of his hand. (01:05:08)
Visible crew/equipment: Towards the end, when the Dude starts getting angry after Walter accidentally scattered the ashes all over him, you can see a black wire under the Dude's shirt going into his pants, most surely a microphone.
Continuity mistake: Throughout the scene where Roland and Maud are sitting on the floor looking through the things in the box from Ash's grave, the head of Maud's hairclip switches constantly from one side of her head to the other.
Continuity mistake: When Holland shows the bartender the dollar bill in the shape of a shirt, he is smoking a cigarette before he takes the cigarette out of his mouth. Holland mentions to the bartender that he made it himself, with nothing in his mouth, but in the next shot, the cigarette is suddenly back. (00:09:45)
Continuity mistake: After the General is murdered, everyone is back in the dining room in front of the statuettes. The Judge mentions that the twisted Owen believes he's doing "justice." Notice the handkerchief in the pocket of the Doctor. It sticks out a lot. Blore says "I'll tell you one thing", and the pochette is now tucked in with just the tip poking out, and it comes out again in full in the next shot. (00:37:50)
Continuity mistake: After Willis rescues the people, he's at breakfast with his son and wife. He slides the newspaper to his son. Close-up on paper (beside orange juice) shows "Bold" typestyle on story slug. Camera pans up to Willis, cuts to son, cut back to newspaper. Suddenly typestyle is italicised (noticeable on "f" in "found"). (01:34:30)
Continuity mistake: When Barry tells Ray to go check if the fisherman is alive, Barry's flashlight keeps changing position from his right hand to his left hand. (00:15:58)
Revealing mistake: When Strahm's phone says "no signal" there is actually a three bar signal. (00:06:35)
Continuity mistake: During the first meeting between Lou and Madeline Kahn, her fur stole changes position between shots almost more often than she changes names. (00:09:30 - 00:10:30)
Continuity mistake: When Sook-Hee first goes to the library, she slides the door open. Once she finishes sliding the door open, she still has her left hand on the door frame. It cuts to an angle from behind where her hand is now off the door frame and being pulled away. (00:21:20)
Visible crew/equipment: When the Jeep is flipping, in one shot, the door flies open and reveals that Ace is wearing jeans. Ace doesn't wear jeans throughout the whole movie showing that this is a stunt double. When the car falls in the parking spot, Greenwall seen through the door is very obviously a dummy.
Continuity mistake: When the crime bosses meet up at the casino, in the exterior shot, there are a few items on the desk including a bottle, an ash tray, a plate with a slice of pizza and a newspaper. Later, when Batman appears and punches one of the crime bosses onto the table, the bottle, ash tray and plate have suddenly moved closer to the newspaper. (00:02:00 - 00:02:28)
Continuity mistake: When David goes into the Dodson Hotel to look for Eddie, the glass door he enters through is completely normal. When he runs out chasing Eddie, he goes out the same entrance and this time the right glass door has a huge hole and is shattered. (00:47:40 - 00:49:35)
Visible crew/equipment: After Matthew and Elizabeth take the pills to stay awake, when they are found Matthew shouts, "David, don't let them touch her," and there's a visible T-mark taped to the floor in the overhead shot. (01:31:30)
Continuity mistake: Inside Lord Peel's study, Poirot asks Lady Westholme what did she do after lunch, since "You did not immediately go for your walk, I believe." Peter Ustinov poses the question with his hands behind his back, but Lauren Bacall's answer answers with the stand-in for Ustinov posing with his hand on his hip. (00:54:40)
Continuity mistake: When Shawn first holds up the jerky to distract the guard dog, he's holding the torch in his right hand and the bag of jerky in his left. We cut to a wider shot and the items have instantly switched hands. (00:26:50)
Continuity mistake: At the start Edgar smashes his car up and kicks his window out and jumps out leaving a bit of glass in the window frame. However after the camera changes, the 2 bits of glass have disappeared. (00:01:05)
Continuity mistake: At the end, when Sam places the last few mini figurines on the hex riser display, note the house's chimney stack faces to the right, but when Sam picks up the display the chimney faces to the left. There are some other difference between these shots, such as the miniature tree under Dash's car goes from full green foliage to sparse, then back to full. (01:45:40)
