Revealing mistake: In the opening credits, there's a shot of the first film where Jacquouille takes the jewels of the dead Duke. The "dead" man moves.
Revealing mistake: When the old couple finally escapes from Godefroy and Jacquouille, you can tell by the way the woman shakes that it's a dummy.
Revealing mistake: After Godefroy yells to the Inquisitors, he touches the wall and it shakes.
Revealing mistake: When Jacquard is being tortured by the Inquisition, the water is not poured in his mouth, the pipe in which the water really flows is sometimes visible.
Revealing mistake: I think this film has been translated, so this mistake is surely only in the original French version. When Jacquouille and Godefroy are in the car with the old couple, Godefroy is sick and says "Je vais vomir glairer". Glairer is the old word for vomir (vomit). It's like he forgot to speak in old French for a second.
Revealing mistake: When Jacquouille cuts the hose, it's smaller during one shot and it seems to be attached to some kind of mechanism.
