When Don stops the car in the middle of the street and gets out to walk home, all the cars previously seen parked end-to-end on the street through his car windows a moment before suddenly vanish, with no cars anywhere to be seen. But, in the very next shot of Jesse Grimm and his wife passing by in their car, the street suddenly changes from being devoid of any parked cars to those same background shots of pre-1940 vehicles parked thickly along the curb.
When Fred Alderson and Don Walling are standing by a fence at the United Airlines gate at the airport discussing who should be the new President of the company, Mr. Alderson changes position between shots.
When Alderson walks over to meet Dudley as he's coming off the plane, the long shot shows Dudley walking amid a group of people, including a stewardess. A moment later, when Alderson reaches Dudley in close-up, all the surrounding people have vanished.
While the board members are waiting for Bullard's arrival, Jesse Grimm says all he's thinking of is a mess of soft-shelled crabs straight out of Chesapeake Bay. As he finishes saying this Walling is shown smiling in a close-up, but in the immediately succeeding medium shot Walling is visibly grim and scowling.
When Caswell is shown looking out the office window after placing his order to sell Treadway stock short, Julius Steigel is seen sitting in his chair, his right arm on the desk and his left hand on his left knee. In the close-up immediately following, his left hand is clutching his coat lapel.
When Caswell goes into the Stork Club, he asks the operator to make a call for him, and the clock behind her reads 5:30, with the big hand halfway between the 5 and 6. After a 30-second phone call, he returns to the operator, where the clock now reads 5:40, but what's worse is the little hand is exactly on the 6. That's not how clocks work.
In setting up for the directors' vote, Erica places six sets of pads and pencils around the table. There are seven directors, including Julia Tredway, who is at that time in Bullard's office next door. Shaw had had her proxy, and she was not expected to appear at the meeting.
When Bullard collapses, and the camera serving as his point of view moves first up, then down to simulate his falling to the ground, there is a briefly visible cut signifying the point where the footage filmed on location in lower Manhattan switches to footage filmed on the MGM back lot, where the rest of the scene was shot.
When the elevator doors, seen from Bullard's point of view, open at the lobby of the office building at the film's beginning, it is obvious that the people in the lobby have been standing still, awaiting their cue when the doors open, as they are clearly standing immobile for a moment before they start to move around the scene.
When Bullard steps out onto the street he turns to the right and calls "Taxi," even though there is no taxi there and he's facing the wrong direction.
Bullard's arms are depicted much too far apart for normal when he's in the Western Union office (the result of having to use two actors to provide "Bullard's" arms, one on either side of the camera that serves as Bullard's point of view).
When Bullard steps into the elevator and turns around to face the door, the point-of-view camera abruptly cuts from the elevator operator to the doors, missing the space between the two that Bullard would have to have seen as he turned.
Although the film takes place on June 19-20, 1953, when Don and Mary Walling are driving home from the plant the first night, all the cars seen parked along the street in the rear projection through the car's windows date from not later than about 1940.
Near the beginning, there is a scene in a city street when the entire crew, camera, and boom are reflected in a store window.
When Dudley pulls off in the taxi at the airport, the camera pans to Shaw watching him in the car. The camera and crew are reflected in the car as it pans up to Shaw's face.
When Don tries to delay the start of the meeting, Shaw states that five members are sufficient for a quorum -- the four men present plus Julia Tredway's proxy (and later, Julia in person). But all Don had to do to hold up the meeting was to walk out, thereby depriving it of the necessary quorum.
On another quorum matter, after the break following the first vote, Don briefly leaves the meeting room to talk to Mary. When he comes back, he's told that Dudley had again placed Shaw's name in nomination for president. But without Walling in the room, the required quorum wasn't present, meaning no business could be transacted. Therefore, Dudley could not have legally nominated Shaw in Walling's absence.
Avery Bullard is scheduled to take "The 5:29" from New York City to arrive in Millburgh, Pennsylvania in time for the 6PM meeting. Impossible timeline.
In the scene in the newspaper office, the clock on the wall reads 9:45. Later that evening, in Eva's apartment, Shaw tells Dudley he can get the 11:00 plane to Chicago. Far too much had happened in between those scenes, aside from travel time between locations, for only an hour or less (in order for Dudley still to have time to make that plane) to have elapsed.
