Continuity mistake: When Thomas and Catherine are having breakfast and his servant Paul brings Catherine's special "green" drink, it changes colors. When Paul has it on the tray and sets it down on the table, it is a very deep olive green. When she goes to actually drink it, it's now a light pastel turquoise blue color. (01:02:20)
Continuity mistake: When TC and Catherine Banning are having breakfast together at TC's house, Paul brings Catherine her green shake to drink. In one of the first shots, the glass is only about two-thirds of the way full, however, in the next shot, when she goes to take her first sip of it, the glass is almost filled to the top. The color of the green shake also changes slightly. (01:02:25)
Revealing mistake: During the glider scenes, they use aerial shots of stuntmen in a real glider and then a prop/dummy one with a blue screen for the close up shots of Thomas and Catherine inside the cockpit. The actual glider has a second rear cockpit control box that you can see in all the aerial shots.The rear pilot is at least 5 feet back from the front one. In the close-ups, with the prop/dummy one, the rear cockpit box is gone and they show Thomas actually leaning on Catherine's back. The actual glider also has a much larger wingspan, fuselage, and cockpit. Again, you see this during the take off shots and all the aerials. When they land in the field and crawl out of the dummy/prop, the tail is only about 5 feet back from the cockpit. (01:04:50 - 01:06:05)
Revealing mistake: During the glider scene when they show the close up of Catherine's face with Thomas leaning over her from behind, waving his hands, if you look at her sunglasses you can see all the white screens, the camera crew, the reflection of his hands, etc. You can see this every time they show a close-up of them from the front of the glider. (01:06:00)
Revealing mistake: During all shots of the actual glider, you can tell very obviously it is two stunt men in very bad, fake looking wigs. The one up front, "Catherine" now makes her look like a football player. He also has on a long red wig that goes to his shoulders, which is longer than Catherine's hair. In one aerial shot, the stuntman sitting in the rear, which is supposed to be "Thomas", has this dark black bowl cut wig that is parted down the middle and slicked to his head. (01:06:05)
Continuity mistake: When they land in Martinique, and are on the airstrip loading up the vehicles, their luggage and the painting go into the second vehicle, a shiny black jeep. However, when they show the aerial shot of them climbing the mountain to Crown's house, the jeep is now painted in camouflage colors. (01:08:10 - 01:08:55)
Plot hole: At the end of the movie when everyone is standing in the gallery looking at the painting now back in place (with the smoke and sprinklers still dripping) they notice that now there is a new painting missing, the one Thomas stole for Catherine. However, none of the other metal wall coverings open or move except for that small side one revealing the empty frame on the wall. This makes no sense why only that one would suddenly open and none of the others. (01:40:50)
Other mistake: When Catherine breaks into Crown's house, her assistants immediately get to work on the security panel. When the first assistant touches the panel, it falls off the wall and he has to quickly push it back into place.
Factual error: The Monet stolen by TC is credited as being the first painting in the Impressionist school, a clear reference to Monet's "Impression: Sunrise" of 1872. However, the painting shown during the entire film is "San Giorgio Maggiore by Twilight," a 1906 Monet painting.
Other mistake: When Thomas' keys are taken and copied, the name "Medeco" appears on the keys. The duplicating machine used is for standard keys and cannot be used for Medeco keys.
Continuity mistake: In the glider scenes, the shots from the front show the sighting window in the canopy placed on the right side of the glider. But in the shots from the side, it is correctly placed on the left side.
Continuity mistake: When Crown's attempting to repeat his golf shot, he flattens the ball into the sand. Then when we see the club hit the ball, suddenly it's on top of the sand.
Continuity mistake: The Jeep and Cobra Mustang are shown covered in mud as they climb the hill to the house in Martinique, however when they arrive at the top, they are clean again.
Continuity mistake: In the scene at the of the movie where Catherine is whispering in the ear of Thomas, you can see that the ear is not from Thomas. Compare the ear with earlier scenes and its clear this must must be someone else.
Other mistake: When Catherine breaks into TC's house and is searching for the Monet there is a scene where she admires The Mirror Of Venus, the footage of this scene has been flipped because the painting is a mirror image of it's actual composition.
Factual error: When Russo and Brosnan are talking at the meal when they first met it is said that he "went from Glasgow to Oxford on a boxing scholarship". Oxford have a firm policy throughout the colleges of only offering academic and music scholarships.
Plot hole: The "titanium-reinforced" briefcase Thomas leaves to block the descending security gate would have had his fingerprints all over it.
Factual error: The Trojan horse is transported into the vault area by a motorised pallet jack. The pallet jack operator is behind the load and his forward vision is totally obstructed by the load. The operator should have been in the front (as required by OSHA). Also they must turn the load around in the narrow hall because later the operator is in the front.
Continuity mistake: The theft occurs on one of the hottest days of the year, as pointed out by the guards. When Katherine arrives that night, she is wearing a coat. The investigation lasts a week or two, and throughout that time, they wear jackets and even top coats. Katherine's breath is frosty in the air a week or so after the theft. The weather apparently went from really hot to really cold in a week or so - NY weather may fluctuate a bit, but not to that extent.
Revealing mistake: In the opening scene, the outdoor setting is supposedly an unusually hot autumn day. However, outdoor shots show several people with jackets, long coats, and almost no short-sleeve tops or shorts.
