Patzer

The troops pursuing D'Aubigny and Madelon as they flee from the farm somehow acquire flaming torches after crossing the bridge.

The cover is from another movie. EDIT: no, it's for the same movie, using the original (American) title. It was changed to 'The Black Book' for the UK'

When Duvall is killed early in the film, a right hand is shown reaching up to him and grabbing him by the throat, then pulling him down. Next is shown the same right hand holding a knife and plunging it toward him. It would appear that the killer (D'Aubigny) has two right hands.

When the troops pursue D'Aubigny and Madelon out of Paris, there are tyre tracks visible on the road.

In a conversation with D'Aubigny, Robespierre states that he turned 36 years old in the month of May. However, during their Reign of Terror, the French revolutionaries changed many things, including the calendar. They discarded the traditional Gregorian calendar (January, February, etc.) in favor of a new, decimal-based system, and called it the French Republican Calendar . There were still 12 months, but now each month had 3 10-day weeks (for 30 days) and all of the months were re-named. What would have been the month of "May" in the Gregorian calendar was changed to "Prairial" in the new calendar. ("Prairial" translates to prairie or meadow.) So being a good revolutionary, Robespierre would have used this new calendar and not the old one when referring to dates. He should have said he "turned 36 years old in Prairial" and not "May."
