- Base-Breaking Character: Jocelyn gets a lot of hate from people who dislike William's constant showering of her with praise, as well as a role as The Obstructive Love Interest - or from people who just prefer Kate. But there are others who think her relationship with William is still very sweet, and she does get some of the best lines in the film. A lot of Jocelyn hate tends to come from Die for Our Ship.
- Big-Lipped Alligator Moment: Just before his eventual defeat Adhemar imagines Wat, Roland, Kate and William delivering an Ironic Echo of the speech he gave William. It's would've made more sense as a Flash Forward, but the director confirmed it was an Imagine Spot.
- Cliché Storm: Some would argue that there isn't very much that's original in this film beyond the main gimmick. Troperiffic clearly comes into play however.
- Crowning Music of Awesome:
He's blonde/he's pissed/he'll see you in the lists/Lichtenstein/Lichtenstein!He's blonde/he's tanned/he comes from Gelderland/He comes from Gel-der-land!
- The songs the rest of the Five-Man Band sing in a tavern about William (to the tune of The Quartermaster's Song ).
Chaucer: He's quick/he's funny/he makes me lots of money/Lichtenstein/Lichtenstein...
- Chaucer has a solo act later, when collecting the group's money from the Frenchmen betting against William.
- The soundtrack in general. The opening set to Queen's "We Will Rock You," concluding with the epic Brian May guitar solo (apparently, in-universe, played on a trumpet). David Bowie's "Golden Years" highlighting the romantic dance between William and Jocelyn, and "The Boys Are Back In Town" as the knights ride in to London for the World Championships.
- The credits also has You Shook Me All Night Long briefly playing.
- Ensemble Dark Horse:
- Prince Edward, big time, all due to him not only being a heroic Magnificent Bastard, but also being Not So Different from William, and finally giving him an Awesome Moment Of Knighting, all to repay his kindness.
- Jocelyn's lady-in-waiting Christiana is quite popular among fans, despite being a side character who has only minimal lines. A lot of fans state that they found her to be prettier than Jocelyn, and use her in ships.
- Kate is easily the most popular member of the supporting cast, despite being the last to join them. A lot of people wish she had been the main love interest, though just as many are happy that she is a prominent female character who doesn't end up as somebody's love interest. And like Christiana, many thought she was prettier than Jocelyn and she's a Launcher of a Thousand Ships.
- Fan-Preferred Couple: A lot of people feel that Will should have pursued Kate rather than Jocelyn.
- Foe Romance Subtext: Quite possibly deliberate, according to the DVD Commentary.
- Genius Bonus:
- There is no record of what happened to Geoffrey Chaucer for a year in his life, and this film is implied to take place in this year. He says I Should Write a Book About This, and indeed 'The Knight's Tale' is the first chapter in The Canterbury Tales.
- Geoff also tells two men that he will get revenge on them by humiliating them in fiction. These two men are Peter the Pardoner and Simon the Summoner, who both appear in The Canterbury Tales too.
- Jocelyn's challenge for Will to lose the tournament and prove his love for her is a direct Shout-Out to the 12th century poem "Lancelot, the Knight of the Cart".
- Hilarious in Hindsight:
- One of Chaucer's Red Barons for William is "the seeker of serenity". Wat is played by Alan Tudyk, star of Firefly and its film adaptation Serenity.
- During the training montage Roland helps Wat to keep a shield steady; that shield has a sigil of a stag on it. Roland is played by Mark Addy, who would later star in Game of Thrones as Robert Baratheon, whose House use the sigil of a stag.
- Ho Yay:
- Launcher of a Thousand Ships: There's fanfiction of Kate/Will, Kate/Wat, Kate/Chaucer, Kate/Roland, and Kate/Adhemar.
- Magnificent Bastard:
This is my word and as such it is beyond contestation
- A protagonist-friendly example in Edward, the Black Prince of Wales. Nearly every bad thing that has happened to Adhemar in this movie has been at least indirectly caused by Prince Edward — or more accurately, by Adhemar's own refusal to joust him. A short time after this occurs, Adhemar is called away to war — on the Black Prince's orders — where he frequently sees the results of the tournaments that have taken place in his absence, all of them being won by William and the fact of it all causing him great anger. Then, when he comes back, he manages to expose 'Ulrich von Lichtenstein' as William Thatcher; Edward's retaliation is to fully pardon and knight William, urge him to fight in the tournament and then cheer him on.
- There's also his speech when he knights William:
- During the final joust, there's WIIILIAAAAAAAAAAAAAAM! It doesn't help that the line is said by William himself.
- Only for Dutch audiences, but Gelderland is a real province in the Netherlands. So its status as a made up homeland for William caused many unplanned laughs.
- Narm Charm: The romantic dialogue is quite silly in places but still works since William's supposed to be struggling with expressing his feelings. Especially hilarious is when he's fumbling over words and manages to spurt out "Your breasts! They are ... below your throat."
- Special Effects Failure: It's painfully obvious when the stuntmen take their lance off-target, just because the script says they lose that round.
YMMV / A Knight's Tale
