Continuity mistake: In the scene where Bill's old boss comes back to see him notice when Bill shoots him and takes the drink. All of the drink comes out of his chest because of the bullet holes. Well notice his shirt is all wet, then in the next scene when he takes off his hat his chest is all dry.
Revealing mistake: During the fight montage, the winner of the first match wins by kicking his opponent in the face. His foot never makes contact.
Continuity mistake: When Harrison Ford is on the rooftop and the suitcase accidentally opens, the Statue of Liberty goes flying off the rooftop and on to the ground, several stories down. In the next shot, the little statue is perched at the edge of the rooftop. Also, the clothes that fly away magically reappear next to the suitcase a shot later.
Revealing mistake: During the big fight scene, you can tell easily that Frank is wearing knee pads (try looking when his pant leg is wet). Construction workers will often wear knee pads for work but most often they wear them on the outside of the pants to save the knees of their pants. (00:58:50)
Deliberate mistake: When Barry is on the phone with Kent for the 2nd time (right before Barry invites Kent to the station), we see Dan (Alec Baldwin) in the booth trying to get Barry to hang up on Kent. Dan holds up a sign that says "dump HIM." Problem is, we are looking at a reflection of the sign, so the sign was actually written backwards, as a mirror image.
Visible crew/equipment: Outside court when Archie is talking to a man, Wanda is standing behind them wearing a fake wig. When the man leaves, if you look in the window behind them to the right, you should be able to see the boom mike operator wearing a red shirt. (00:38:25)
Visible crew/equipment: When Julius enters the supermarket parking lot, in the long shot we can see the stunt ramp used to lift the driver's side of the car, to go into ski mode. In this and following long shots of the stunt, we can also see the window roll cage bar directly behind the front windshield (the obvious stunt driver grips the roll bar with his left hand and steers with his right hand), as well as the top of the seat supports behind the front headrests. (00:30:55)
Revealing mistake: When Jemma enters the headshrinker's laboratory, there is a table with three heads on it each encased in glass. When it goes in close-up on the middle head, you can see that the table has a hole where the actor can slip in his head.
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: The ruler in Tess' hands instantly changes design. It looks like she flipped it over between shots, but without any time or reason to do so. (00:19:20)
Continuity mistake: The 3 girls lock Sadie Shelton in a closet and then bring a chair to secure the door and Rose sits. A couple of seconds later, Rose is standing again holding the door. (01:28:05)
Continuity mistake: When Bill Pullman is poisoned he has a defined red cross painted on his forehead. He stumbles around for a while and the cross smears to the point where it looks like a big red blob. But when he finally dies and looks at the camera, the cross isn't smeared at all. (01:16:35)
