(at around 1h 08 mins) When the chandelier falls, Andre is first shown rolling away well to his right just as the rope is cut. His back isn't touching the floor. He is then shown from above rolling to his LEFT. While looking up at the falling chandelier his back is firmly planted on the floor. The final shot again shows him rolling to his right in a slight repeat of the first shot.
When Andre's sword slices Noel's upper right arm, there is no tear in the fabric, and no blood until Noel puts his left hand over his arm leaving finger shaped blood spots, and which change size/shape throughout the rest of the sword fight.
When Moreau, as Scaramouche, announces to the audience that the Marquis de Maynes is in attendance, there is a close-up of Aline (who has recognized Moreau) putting her left hand to her head and saying that she is ill. But in the cut to a long shot, her hand is below her neck.
Assuming the pamphlet is written in French, a split infinitive is an impossibility. Unlike English, French infinitives are a single word.
At the very end of the motion picture, Lenore turns away from the window where she has just tossed an exploding bouquet to Scaramouche and we discover that her newest lover is none other than Napoleon Bonaparte. However, the appearance of Napoleon in the scene is incorrect since it shows him as he appeared after 1806. The motion picture is set in pre-revolutionary France. At that time, Napoleon was thin and had long hair.
Andre's legs are too thick for him to be a great sword fighter.
The Gavrillac coat of arms has the scroll with the family's name crossing the middle of the shield. That is not the right place for it; the scroll should be at the foot of the shield, and surrounding its contour.
When Lenore comes to seek Aline's aid in saving Andre from Noel Aline's little dog barks at the foot of her bed but shows no sign of barking other than at the very beginning but the sound continues with no other movement. Dogs move their heads when they bark.
The second view of Moreau through the ceiling trap of the cabriolet shows a horizontal view of clouds when the clouds supposedly are being viewed from beneath.
The soldiers wear uniforms from the Napoleonic era, not the pre-Revolution period.
During the final sword fight between Scaramouche and the marquis, when Andre falls off the balcony, a safety rope is visible under his cape.
Characters fail to recognize Andre's voice when he is disguised as Scaramouche.
Early in the film, Andre criticizes Phillippe's letter on its grammar, citing a split infinitive. Andre then tells Philippe to "boldly go outside", thus committing a split infinite himself.
