Goofs

When Ganimard is in the wine store the orientation of his closed right hand on the table changes between the two-shot cut where he has it in the middle and the close-up where he has it at the edge.

The amount of grease on Dubose's arm after fixing Stacie's car brakes changes from the three-shot cut to the cut where he opens the car door for Arsene and Stacie.

The orientation of where Dubose has the cloth on the kitchen knife changes between the two-shot of him and Arsene at 30:21, to the close-up.

When Stacie is in the trophy room, Charles is holding the rifle upright and cleaning it. However, in the next immediate cut, he is now holding it horizontally just above his lap.

At the end of the film when Ganimard is taking Lupin to Scotland Yard in a taxi driven by Dubose; the constable casually enters the taxi and puts the cuffs on Dubose. However, the taxi was already moving at a high speed before he entered the vehicle therefore it is impossible for this to have happened.

When the Scotland Yard official offers Ganimard a cigarette, he says a bit of dialog about smoking has been a bad habit since he was a small boy. However, in the next cut which is a close-up when the official lights the cigarette, he paraphrases the same dialog about being a habit since he was a small boy. They partially merged two takes of the same dialog.
