The investigating judge calls to interview the General, and when he gets there, he's in a different suit.
(at around 1h 16 mins) When Nick (Georges Géret) is sitting up in his hospital bed, a front shot with his arm by his left side cuts to a wide shot where his arm covers his stomach and rests on his right side.
(at around 46 mins) When Clotilde Joano and her male colleague are crossing the roadway, they do so behind a street cleaner vehicle with its water jets on, as shown in the street level view. The next cut shows an overhead view with both the street cleaner and the characters continuing on their way just seconds later, and the roadway is completely dry.
After hitting Z, Vigo and Yago escape on a three-wheeler. Shortly thereafter, the driver Yago is captured by a policeman. The policeman searches him and finds a truncheon. When the guard uses the truncheon on Yago's chest to keep him away, the stick clearly flexes.
While visiting the witness in the hospital, the judge (Jean-Louis Trintignant) holds some photos in his hand. One of them is a photo of one of the hoodlums who attacked Georges Pirou (Jean Bouise). But this photo will be taken later on the street by the journalist (Jacques Perrin), who investigates the members of the secret organization.
After Nick is hit on the front of the head, he holds the back of it.
