It is loosely based on the Mark Twain 1889 novel A Connecticut Yankee in King Arthur's Court, previously filmed by Disney as Unidentified Flying Oddball in 1978.

In the Los Angeles suburb of Reseda, 14-year-old Calvin Fuller is at a baseball game, standing at bat for his team, the Knights, ready for yet another strike out.

When the earthquake hit, Calvin had just grabbed his knapsack, a fact that enables him to dazzle the people of Camelot with his futuristic "magic", including an introduction to rock and roll via CD player, a Swiss Army knife, and inline roller skates.

His work wins him adulation and renown, but it also rouses the jealousy and disdain of Arthur’s advisor Lord Belasco, who is secretly scheming to take over the throne.

Meanwhile, Calvin finds himself spending time and developing a crush on young Princess Katey, while her elder sister, Sarah, is secretly in love with Sir Kane.

He is greeted by his teammates, including Katey, and is looked on by Arthur, who is whittling a piece of wood with a pocketknife – the same knife Calvin gave to him.

The ball meanwhile sails into a chasm where Merlin catches Calvin’s home run and then breaks the fourth wall by stating "Taught that kid everything he knows."

The consensus reads: "Disappointing even by the relaxed standards of live-action children's entertainment, A Kid in King Arthur's Court stands as a rare near-total misfire from Disney.

The cast also included Rhona Mitra as Scheherazade, Nicholas Irons as Ali Baba, James Faulkner as Luxor, Taylor Negron as the Genie, Aharon Ipalé as Aladdin and Diana Kent as Jasmine.
