In Chapter 5 when Henie, Jean and her father, Gregory, escape from the hospital, their car is parked right in front. They hop into the car and drive off. In hot pursuit are henchmen Moore and Boyle. As they run to their car, it is suddenly parked right in the same spot that the other car was parked in.
In chapter 9, henchmen Moore and Boyle are hanging out of sight onto the outside of the car that Henry and McCoy drive away in. How the two of them (including the viewers watching this) don't see them hanging on is unbelievable. It's also unbelievable that they are doing this while the car is speeding down the road.
In both chapters 1 and 11 the same scene is used of the plane in a spiral dive.
The long shot of the scene depicting John Wayne as Craig and Roy D'Arcy as Gardener are clearly shot with the men on a ferris wheel, but the closeups of both men are mismatches and none of the bars and struts of the ride can be seen since both actors are clearly on the ground and not moving.
