Kate & Leopold (2001)

Factual error: It's not just the date of La Boheme they have wrong. Pirates of Penzance didn't premiere until 1880 and it was the apprentice who found love with the Major General's daughter and not, as stated, the Pirate King. (00:33:00)

Leopold: As I see it, Patrice has not an inkling of your affections, and it's no wonder. You, Charles, are a merry-andrew.
Charlie: A what?
Leopold: Everything plays a farce to you. Women respond to sincerity. No-one wants to be romanced by a buffoon.

Trivia: The real Leopold, Duke of Albany, died of hemophilia in 1884 at age 31.
