Continuity mistake: In the scene where Frank is pretending to be a Doctor at the bedside of the kid who has just had a bicycle accident a nurse hands him a swab. While he talking to the other Doctors the swab is visible but when the shot changes his arms are suddenly folded and we can no longer see it.
Continuity mistake: When Frank Jr. and Sr. are going to the Chase Manhattan Bank, the same white truck drives behind them twice.
Other mistake: One of the end credits is "saxaphone solo." It should be "saxophone."
Continuity mistake: In the scene after Frank gets his uniform, when he is walking on the sidewalk the overhead shot shows a wet sidewalk, but in the next shot you can see behind Frank that the sidewalk is now dry.
Factual error: In the lunch scene in the fancy restaurant with Frank Sr. and Frank Jr., the crystal goblets are of a pattern that wasn't available in the 1960's. The pattern is Mikasa Parklane, which I believe became available in the late 1980's.
Character mistake: Carl, carrying his gun, goes up the outside staircase before entering Frank's apartment. When he encounters the frightened cleaning woman, he flashes his F.B.I. badge at her to identify himself. However, he only shows her the back of the black I.D. wallet, which has no markings on it.
Continuity mistake: There is a scene where Leo is at a hotel and meets Jennifer Garner, the 17 model. Then when he is recruiting flight attendants at a school, you see Jennifer Garner again but this time as one of the school girls.
Suggested correction: She is not in the recruiting scene. Jennifer Garner is featured in that one scene at the hotel, and is never seen in the movie again.
Continuity mistake: When he pretends to be a doctor, and a he has to give advice on what to do with this patient, a woman gives him some kind of tool. He holds it in his hands, and towards his face, in a 'thinking' pose. Then the camera changes and the object is suddenly gone. The camera then jumps back to the previous position where he had the tool, but it's also gone in that frame. He's now just having his arms crossed.
Factual error: No airport in the world has runway 44. They are numbered 01 to 36.
Factual error: When Carl looks at a map over Europe, the borders of the countries are incorrect at the time: Germany is shown as one country, but it was divided into east and west in the sixties. Czechoslovakia was one country in the sixties, however it was divided into Czechia and Slovakia on the map, as it was at the time the movie was made.
Continuity mistake: After Frank Jr. receives some checks for his 16th birthday he hugs his dad. Jr.'s head rests on his dad's right or left shoulder, depending on the angle.
Continuity mistake: In the plane, during Carl and Frank's chat on how did Frank pass the law test, the pillow in between swaps positions between angles.
Continuity mistake: When Frank Jr. takes his father to a fancy restaurant, his hair keeps swapping between brushed backwards or with a fringe on the left side.
Continuity mistake: Going to school, Frank takes a cigarette off his mom's hand and throws it over the window. On the first angle he takes his head out of the window, but on the next angle his head is inside, as if just the torso had made the movement.
Continuity mistake: When the show 'To tell the truth' starts, the host has his hands apart and raised. A frame later they are flat on the counter and his fingers crossed.
Factual error: In the scene where Frank is tearing up Park Avenue in his "James Bond" sports car, a modern "NYC" lamp post banner is noticeable in the background.
Continuity mistake: When Frank is having lunch with his father and offers him a Cadillac, in some shots Frank's right arm is over the table, but in others he has both arms hanging.
