When the camera is facing Guy and Mily as they are watching the religious procession, he is standing to her left. When the camera is behind them, he is standing to her right.
When he meets Guy van Stratten, Jakob Zouk's beard is much heavier in close-ups.
When the small plane is shown in long shots, it has a solid roof over the cockpit, but when Arkadin is shown on the radio calling the Barcelona tower in closeup, he is sitting in a plane with an open cockpit.
In the Corinth version when Raina, after leaving the club, walks up to her father's car and says hello, Stratten is next to her and the car. However, in the reverse shot, Stratten is nowhere near her or the car.
A shot near the end, with Raina resting her head on the steering wheel of her car, is extended by looping the film several times. This becomes obvious because a man's shadow keeps appearing and disappearing in a gate behind her.
When Guy is in the cafe talking to various customers about how to meet Arkadin and Raina, there are people not involved with the film who are standing outside a window and peeping in on the shoot.
When Guy is at the airport talking to Raina about her dad being Russian and his amnesia, many of the extras in the background are behaving out of character as if they were an audience by looking at the camera and the main actors.
In the Corinth version when Raina and her dad take off in the car, there is a crowd of people far in the background hanging outside a theater in front of the entrance. However, the crowd is just standing there looking at the camera and the action as it unfolds. Apparently, they used regular folks as extras and instructed them to just stay there.
In the Corinth version when Raina's father's plane flies over her and Stratten, the same footage used the first time the plane is seen is also used for the second time the plane is seen.
When Mily slams the phone booth door on Bob, he says something with a frustrated look. However, the audio mutes out briefly; therefore, one doesn't hear the door slamming nor what Bob uttered.
When Raina is telling Guy about her dad's secretaries, she can still be heard talking to Guy when she drives off; however, her mouth is closed.
The shadows of the crew and camera operator are clearly seen at the very end of the film when the convertible drives off.
In the Corinth version during the religious procession, when Raina talks to Stratten about the girl in the sweater who was waving, she is referring to Mily. However, when Mily is first seen, she is not waving nor is there any indication that Mily had even spotted Stratten. Additionally, Mily was not wearing a sweater.
In the Corinth version when Arkadin arrives at the building where Stratten and Zouk are held up, his car stops between the building and the street musicians. However, in the next cut, Arkadin walks through the musicians and toward the building. This makes no sense because logically he would have been able to go directly to the building without any obstacles. This is made even more evident when he returns directly to the car without going through the musicians.
When Mily opens the door to the telephone booth looking for Stratten, it turns out that it is occupied by Bob the Marquis, and she then apologizes to Bob for opening the door. However, the phone booth door is made of clear glass, and Bob was facing the door; therefore, she would have easily been able to tell that it wasn't Stratten in the booth.
