Continuity mistake: In the opening scene when Oz is brought in to be fired, he first approaches the desk and before he sits down, is standing in between the desk and the chair. In the reverse shots from behind him, he is standing behind the chair, not in front of it. (00:01:45)
Continuity mistake: In the scene where Osbourne is getting demoted because of his drinking problem, a gold pen keeps appearing and disappearing on the desk. (00:01:45)
Other mistake: In the scene where George Clooney is standing in front of their house watching his wife leave for the book-signing tour, the front door of his house is open. You can see the trees inside the front door as if the trees are inside their house. (00:37:40)
Continuity mistake: In the first meeting room at the Russian Embassy, the picture behind Linda and Chad changes from a blue framed portrait of what looks like Yeltsin to a portrait of Putin. (00:45:50)
Other mistake: The date on the surveillance footage from the camera in the Russian Embassy says 01.05.08, implying that it is either January or May (depending on which date notation is being used, American mm.dd.yy or Russian dd.mm.yy). However, it is fall/autumn outside, as there are dead leaves everywhere. And when Katie calls Harry we can see that his cell phone shows 17/9/08. (00:48:00)
Continuity mistake: After Chad Feldheimer and Linda Litzke leave the Russian embassy and pull up to Hardbodies where they work, there are no numbers above the door. Right after they enter, the interior shots show 1665 backwards above both sets of doors. (00:48:50)
Factual error: The fitness center is supposed to be located around the D.C. area. Inside the fitness center, in one quick shot, at the top left part of the screen, out the big window, across the busy highway, you can see the sign of a camping supply store called Campmor. The one and only Campmor retail store is located on rt 17N in NJ, about 240 miles away from D.C. (00:48:55)
Continuity mistake: When George Clooney and Tilda Swinton are eating in a restaurant part-way into the film, throughout this scene Tilda Swinton's spoon appears and disappears. (00:50:05)
Continuity mistake: When Linda is trying to get Ted to help her, the front shot of Ted's hands shows no ring, but the back shot of his hands shows a ring on his left hand. (01:19:30)
Continuity mistake: When George Clooney is running, there's a shot of him in the neighborhood with the back of his shirt drenched. When they show him inside the house shortly after, the sweat stain on his back is significantly smaller.
Factual error: The layout of the Cox's house doesn't make sense. The house is an end-terrace - stairs on the right side (from the front). The stairs rise to the back, and perform a 180 degree turn. The first door on the left is the Cox's bedroom. The wall opposite to the bedroom door would be a solid wall - the partition wall to the neighbouring terrace. Instead it has a well lit window.
