Directed by: Michael Mann
Starring: Madeleine Stowe, Daniel Day-Lewis, Eric Schweig, Russell Means
Deliberate mistake: Rhododendrons, visible in the opening scene and mentioned specifically in the shooting script, do not grow in the Adirondacks.
Suggested correction: Several varieties of rhododendrons absolutely grow in the Adirondacks and are native to the region. Rhododendrons are native as far north as Nova Scotia.
Revealing mistake: Near the very end of the movie, when Magua has taken Uncas' love interest (Madeleine Stowe's character's sister) and he is taking a path through the mountain, Daniel Day-Lewis runs up a path and brushes against what seems to be a rock. But, the grey coloured "rock" seems to be a prop and moves like a piece of cloth.
Question: At the fort they cover their cannons with sheepskin. Why?
Answer: During inclement weather, dry sheepskins were used to keep rain from entering the barrel. During battle, wet sheepskins were used to cool down the barrel to decrease the likelihood of the powder exploding prematurely.
