Corrected entry: When Huck and the bratty blonde girl are talking about England, the girl says that George IV is the king. George IV reigned from 1820-1830, but the story of Huckleberry Finn is thought to take place in the 1830's or 1840's, not as early as the 1820s. (01:08:30)
Corrected entry: When The Duke sees the dead Mr. Wilks in the coffin the deceased's mouth is wide open. The Duke closes it without any effort, as if there were no such thing as rigor mortis. (01:07:20)
Correction: Rigor mortis usually lasts between one and three days, so depending on how long Mr. Wilkes had been dead, it might have already passed.
Correction: It's only a mistake if the movie is not set in the 1820s. The books setting could well be slightly different.
