Trivia: Several of the named knights were, in fact, real, though many of them are from different time periods. Ulrich von Lichtenstein was a knight and author who was said to have invented the concept of chivalry and courtly love. Piers Courtenay was a descendant of Edward I, born in the 15th Century. Sir Thomas Colville, Edward III's disguise, was a knight from the 13th Century.
Trivia: There was a period of about a year in Geoff Chaucer's life when historians have no records of what happened to him. This film is supposed to be set in that year.
Trivia: Ulrich von Liechtenstein was a real knight, and regular jouster. He boasted that he would give a golden ring to any knight who could break a lance on his armour, giving away 271 in total, but remaining undefeated.
Trivia: Geoff Chaucer threatens to immortalize the summoner and the pardoner in literature, and the real Geoffrey Chaucer did just that in his Canterbury Tales. The Pardoner and Summoner were portrayed as two of the most corrupt and vile people imaginable in Medieval society. They are also homosexual lovers.
Trivia: The film has an interesting tech/science joke. Kate has discovered how to carbon temper steel making it vastly stronger and lighter. Of course, no smith back then would have listened to a woman about her techniques, so that advance wasn't invented until much later.
Trivia: There is an extra scene after the credits - I won't say what happens but let's just say that it's pretty disgusting.
Trivia: The production crew used homeless people from Prague as some of the extras in this movie.
