Audio problem: When Sir Rodney Ffing is disguised as Robespierre, his lips don't match what's being said. Plus when him, Darcy and Pommefrit are leaving, as he says "You two, come with me", his lips aren't moving at all.

Continuity mistake: When Charles Hawtry is about to be beheaded, someone comes up to him saying they have a message for him. He replies with, "Toss it in the basket and I'll read it later." So she throws it in the basket, but in the next shot when you see an overhead view of Hawtry, the basket is empty.
Duc De Pommfrit: Come here, you little vixen.
Desiree Dubarry: Oh, get off! Stop it.
