Sir George (Gary Lockwoodnote ) is the foster son of Sybil (Estelle Winwood), an elderly witch. Not much is said about his background, other than that his parents are dead and he is of Royal Blood. He is secretly in love with Princess Helene (Anne Helmnote ), who is kidnapped early in the film by the evil wizard Lodac (Basil Rathbone).
George wants to go on a quest to liberate his lady love, but Sybil believes he is too young. She comforts the youth by showing him a magic sword, a steed, a suit of armour, and a group of magically frozen knights — all his to command when he turns 21. But the impatient George tricks Sybil into a locked underground cellar and immediately takes off with his magical implements and the revived company of knights.
Sir George and his party then appear before the king, who looks like Grady from Sanford and Son, and insist on journeying to Lodac's castle to rescue his daughter, even though this angers the knight who had previously been given the task. To save the princess Helene, George and his companions must go through Lodac's seven curses.
The film contains examples of:
- Back from the Dead: Sir George's band of knights somehow come back to life.
- Maybe Lodac's curses had No Ontological Inertia.
- It's implied that Sybil did it somehow with Lodak's ring.
- Cheese-Eating Surrender Monkeys: Subverted; the French knight is probably the bravest out of the crew (except perhaps for Patrick). He almost gets done in by way of a different French stereotype, however: the horny Frenchman.
- Credits Gag: The person who worked the dragon puppet is listed in the credits as a "dragon trainer".
- Death Is Cheap: The party of knights drop like flies throughout the film, then are resurrected at the end.
- Disposable Woman: The two princesses before Princess Helena.
- Dwindling Party: George revives six knights from all parts of Europe to aid him on his quest, (Spain, France, Germany, Scotland, Ireland, Italy), two of them die when facing the first of the seven deadly challenges between them and the wizard's castle.
- Engineered Heroics: The entire kidnap plot is all a plan between Sir Branton and Lodac so Branton can "rescue" the Princess. Too bad for him that A) George and his knights join the party and B) Lodac has no intention of honoring the deal.
- Evil Plan: Lodac kidnaps Princess Helene and holds her for ransom as vengeance for the King killing his sister.
- Forced Transformation: Lodac turned the Hag into a spider.
- Good Witch Versus Bad Witch: Sybil v Lodac. Notably, there never is an actual "magic duel", as Sybil states early on that she would be no match for Lodac. She defeats him in the end only after pilfering his magic ring during a moment of distraction.
- Heroic Sacrifice: Patrick, already dying from the fifth Curse, sacrifices himself to help George escape.
- Invincible Hero: George. His armor protects him from anything, his horse can run at super speed, and his enchanted sword can kill an ogre and a dragon in a single stab. In fact, it takes Sybil depowering him by accident to introduce anything resembling danger to the guy.
- Flat Character: George's companions, whose characterization ends at "loyal and brave". Most only have enough dialogue to introduce themselves to the King. Even Patrick and Dennis, the only knights with an appreciable role, get only rudimentary traits beyond their courage and loyalty (Dennis is a horny Frenchman who can't pass up a pretty girl to save his life, and Patrick is said to be the most devout).
- The Lancer: Sir Patrick is the closest of the Knights to George. He's always by his side, among the first (and most frequent) to voice his dislike and distrust of Branton, and is the last of the Knights to fall while aiding George on his quest.
- Mauve Shirt: George's team of knights all exist to be taken out by Lodac's curses. Sir Branton even lampshades it, commenting to himself how there's "seven swords" accompanying him to take on "seven curses".
- Multinational Team: George's band of knights. We have Spain, France, Germany, Ireland, Scotland, and Italy represented. It is probably not coincidence that the seven knights are named for the patron saints of said nations. George himself, and the general story, are loosely based upon Saint George of England.
- Named Weapons: The titular sword is named Ascalon.
- New Powers as the Plot Demands: Sybil mentions most of the items' magical powers, but a few just come out of nowhere, such as the sword being able to move on its own to rescue George, or the Hag-banishing shield.
- Obviously Evil: Lodac. Pitch black sorcerer robes? Check. Blood red turban? Check. Unbelievable sadism and zero empathy for others? Check!
- Our Dragons Are Different: Classic Western style, fire breathing and all.
- Parental Abandonment: George is an orphan of Royal Blood after his parents die of the plague.
- Poke in the Third Eye: Lodac doesn't appreciate Sybil scrying on him with her magic mirror, so he undoes its magic (which resumbles an untuned television in practice) after taunting her.
- Power Glows: George's sword glows when it does... whatever exactly it does. Also his shield when it's banishing Hags.
- Power Perversion Potential: The pond George has been using to "watch" Princess Helene.
- Redshirt Army: George's knightly companions are mainly there to be cannon fodder to show how dangerous the journey is.
- Religion is Magic: When he dies, Sir Patrick is able to save George from the current curse through the power of his faith.
- Rewarded as a Traitor Deserves: After returning Lodac's ring, Sir Branton gets turned into a hunting trophy by Lodac.
- Ring of Power: Lodac's, which he lost. Branton found it, and it's how he's getting Lodac to help in the princess kidnapping gambit. In the end, Sybil gets it.
- Rule of Seven: Lodac possesses seven curses to face all challengers to his power, including himself. Sir George and his entourage of knights make up a party of seven, as well. Sir Branton assumes that these numbers will cancel each other out and leave him the sole victor with Princess Helene, but his pride prevents this outcome.
- Skinny Dipping: Princess Helene is introduced swimming nude in a lake, while George watches using the magic pool.
- Swamps Are Evil: They suck up your dudes and strip them to the bone.
- Take Our Word for It: Lodac notes that it's Patrick's faith in God that helped him free George from the fifth Curse. However at no other point in the film do we ever see Patrick demonstrating his faith.
- Too Dumb to Live: Sir Branton. He cannot be harmed by Lodac while wearing his Ring of Power. Instead of using this protection to finish off Lodac himself, he trades it for Princess Helene as per his agreement with Lodac, despite him questioning Lodac's own word and betraying his actual allies. This is especially bad since Branton had actually pointed out how stupid he would have to be to do this in an earlier scene.
- While the ring does protect Branton by wearing it, Lodac states that he has no way of using the ring's full potential. It is possible therefore that if Branton simply tried to run Lodac through, he may have ended up as a wall mount anyway.
- Upgrade Artifact: The titular "Magic Sword" and George's horse. As well as Lodac's ring, which turns him from one of the strongest wizards to THE strongest, and puts Sybil on his level when she gets it.
- The Vamp: The Hag, when she's putting on the Fanservice.
- Virgin Sacrifice:Lodac: My little pet will be hungry again in six days' time.
Crow: Er, five days time.
- Voluntary Shapeshifting: Lodac and Sybil have the ability to change into birds, and Sybil can also change into a black panther. She uses the latter to kill Lodac at the end of the film.
- We Are "Team Cannon Fodder": George's knights exist to get wiped out by the curses.
- We Hardly Knew Ye: Ulrich and Pedro are the first of the knights to die.
- You Have No Chance to Survive: Lodac's final lines are spent monologing about how George and Helene are about to be destroyed by the seventh and final curse — Lodac, himself.
