Continuity mistake: Many times through out the film the red bag that contains all the money is not seen with the main group, even though they supposedly keep it with them at all times. The most noticeable example is when the two main characters first fly into Spain in the balloon and when the interior of the basket is visible the bag has simply vanished, but they have it again later.
Continuity mistake: When Luz is talking to Jet on the phone for the first time, from the front she's fiddling with the phone cord with her left hand. When it cuts to the reverse, however, her hand is flat on the desk.
Continuity mistake: When they are dancing the king's earring is on his left ear then it somehow jumps across to the other ear.
Continuity mistake: Although the assassin and the ambassador are seated in the same tier of boxes, the assassin's view of his target through the opera glasses is from below and not from across.
Continuity mistake: In the final shot, just as the credits are rolling, the British warships are sailing away with the sun setting behind them. In an earlier scene the radio commentator says that the sun is setting and a shot of the sun touching the surface of the sea is shown.
Continuity mistake: When Frankie punches Barakov, pushing him through the window, not only do you see the wires lifting him, but it is obvious that the inside of the building is a studio set as not only does the window get broken, but also the wall above it is torn. The wall is obviously made of paper and the scenery outside the building is a painted backdrop. And when the angle changes to outside the building, only the window is broken but the wall is intact.
Continuity mistake: In the scene where Van Gogh cuts his ear off, he smothers his right ear with a towel to stop the bleeding. As the movie continues, we notice that throughout the whole movie his left ear was the one missing not the right ear as initially portrayed.
Continuity mistake: In the scene where Robert Wagner and Buddy Ebsen are in a fox hole note the position of the bullets in their boxes. One lot is further away from the pole holding the shade canopy and in a closer shot it's now changed position and closer to the other bullets. The shot then changes again and the bullets are back to their original position as seen earlier. (01:19:25 - 01:20:50)keiko
Continuity mistake: When the shoemaker swats the elf, he has a fly swatter in his right hand. When the elf tells the shoemaker that he has been sent to take all the elves back, we return to the shoemaker and he is no longer holding the fly swatter.
