"The Knight's Tale" is one of the chapters in Geoffrey Chaucer's, "The Canterbury Tales."

Ulrich von Lichtenstein was a real knight, but not such a great one. He boasted that he would give a golden ring to any knight who beat him in the joust. In one month he gave away 271 rings.

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.

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.

Paul Bettany developed laryngitis from all the yelling he had to do.

The scene where Mark Addy says "Yayyyy" because the audience gives no reaction to Chaucer was improvised by Addy because the extras didn't speak English (they were Eastern Europeans) and had no idea when to cheer.

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.

This was a story written by Geoffrey Chaucer. At the end, Chaucer (the man that makes the announcements before the jousts) says something along the lines of "I think I'll write this down," which in real life he does, forming the basis for this movie.

There is an extra scene after the credits - I won't say what happens but let's just say that it's pretty disgusting.

The Black Prince is shown at the battle of Crecy. At that time, Geoffrey Chaucer would have been barely in his teens.
