Continuity mistake: When William is let out of the stocks you see him take his hands out of the holes, however in the next shot you see him take his hands out of the holes again. (01:53:30)
Continuity mistake: In the scene where William gets his knighthood, it shows William from the front with his arm up holding Chaucer's hand, as he has just come out of the stocks and is about to kneel, when the shot changes it shows the prince, and William from the back with his arm down, then when the shot changes back 2 William's front, his arm is up holding Chaucer's hand, then when the shot changes back 2 the prince - arm down, and when it changes again back to William - arm is up, just letting go of Chaucer's hand. (01:53:40)
Continuity mistake: Just prior to when Prince Edward is Knighting William (after William takes a knee), they do a wide shot to show where everyone is, and Chaucer is sitting in front of the stocks directly in the middle. After he is knighted, Chaucer is sitting to the left of Roland (as you face the stocks) and then at the end of the scene, he is back in the middle. (01:54:35)
Continuity mistake: In the scene where Sir William (Heath Ledger) is preparing to fight Adhemar (the "bad guy") he is talking to Geoff Chaucer. In the background in the stands, you see a figure in a yellow dress (Jocelyn) talking to a figure in brown clothing (John Thatcher). Jocelyn leans over to speak to John, and then they sit down. In the next shot, when William is told that Jocelyn had arrived, he looks into the stands, where Jocelyn is again standing, leaning over to speak to John. They then sit down again. (02:00:20)
Continuity mistake: At the end of the film, when Heath Ledger has defeated Rufus Sewell, he is seen with a puncture wound on the upper right side of his chest. In close up the wound is seen to be bleeding through a hole in his jacket but in the next shot it is shown just as a red blob on his jacket with no hole in it. And when the jacket falls open you can see there is no wound underneath. In the next close-up the hole in the jacket is back. (02:01:05)
Continuity mistake: When Geoffrey jumps up to give his introduction during the final joust, he runs to the stands and you can see Jocelyn and Sir William's father just sitting next to each other. The camera angle changes and you now see Jocelyn's arm wrapped around John Thatcher's. (02:02:05)
Continuity mistake: When Chaucer is introducing William at the end of the movie, he stands on the arms between the chairs of Prince Edward and the lady, a foot on each arm. When it cuts to a side view showing William's father to the Prince, Chaucer is no longer in between the chairs. Not to mention the fact that the Prince is looking at the railing (where Chaucer just was). The very next shot, he is back between the chairs. (02:03:05)
Continuity mistake: Right before the final joust the camera is panning back and forth between Sir William and Count Adhemar. Each time the camera is on Adhemar you see about 4 to 5 flags waving behind him. When they start charging towards each other, you only see about 2 flags. (02:03:45)
Continuity mistake: During the last jousting scene against Adhemar, William has a piece of red string tied around his neck. While he is riding down to knock Adhemar off of the horse, you see the string in one shot, but not in another, then it is back again. (02:04:35)
Continuity mistake: When Sir William gets off his horse after defeating Count Adhemar, the hole and blood on his right shoulder disappear and then reappear. (02:06:40)
Continuity mistake: As the scene in which William is knighted begins, Roland takes a position to his right, holding a staff in both hands, raised to his right. Once the Prince reveals himself and approaches, Roland has the staff touching the ground, which is fine, he may have done that as a response to the Prince. Cut to a close-up of Roland's face an instant later, now he looks worried and the staff is raised to his right. Cut back to the Prince an instant later, and the staff is back on the ground.
Continuity mistake: During the last match between William and Rufus the sun changes between shots.
Continuity mistake: In the scene where William is having a discussion with Jocelyn in the stables, look at the top left corner of his breastplate. Between shots it changes from being tucked under his shoulderplate to being on top of it.
Continuity mistake: At the end of the film, when Heath Ledger has defeated Rufus Sewell, the amount of wood pieces in the air changes between shots.
Answer: The reason he is so agitated has to do with the manner in which he won the tournament. If you'll recall, William states, "I'll not be champion until I beat Adamar." Adamar had forefeited beforehand, (not wanting to joust against royalty) therefore not giving William a true victory. After his half won victory, Jocelyn's (Shannon Sossamon's character) inane chatter just rubbed him the wrong way. It had nothing to do with what she was saying...if anyone had spoken to him he would have reacted in the same way.
