Factual error: The French Cuirassiers are all carrying lances. Cuirassiers did not carry lances - their primary weapon was the sword.
Factual error: In the dancing scene in the pub, the band playing contains a tuba. The tuba was not invented until the mid-1830s.
Factual error: At least in two different shots people are humming Johannes Brahms' lullaby. This shouldn't be possible, because Brahms didn't compose his lullaby (op49. No 4, Wiegenlied) until 1868.
Revealing mistake: The "metal" axe in his hand bends as Jacob flies through the window of the tower and smashes into the floor.
Sasha: It's all right! They're the brothers Grimm! People talk about them in Marsburg! They're famous!
Will: Right you are son! The famous brothers Grimm. Look at this strapping young man.
Gregor: "He" is my daughter.
Will: And a fine wife he'll make some lucky man.
