A Kid in King Arthur's Court

A 1995 film based loosely on A Connecticut Yankee in King Arthur's Court.

A young kid, Calvin Fuller (Thomas Ian Nicholas) is playing a baseball game when an earthquake opens up a rift in the ground and transports him to the 6th Century, where he meets up with King Arthur. Along the way, he falls in love with one of King Arthur's daughters, tosses off a lot of anachronisms in failed attempts to be funny and ends up getting transported back to his baseball game.

Has a sequel entitled A Kid In Aladdin's Palace.

Tropes present:

 * Adipose Rex: King Arthur
 * A Little Something We Call "Rock and Roll": Played straight with Calvin's Discman.
 * Then Subverted later when he pulls it out again, only to use the lens inside to reflect light and blind a guard.
 * What does he use when challenged to combat? "I choose... Combat Rock!" Cue guards holding their ears while Calvin rocks out.
 * Anachronism Stew: Attempted for laughs and failed miserably.
 * Badass Grandpa: Arthur
 * Badass Princess: . Princess Katie starts out this way before suffering one of the most ridiculous cases of Chickification you'll ever see anywhere.
 * Bamboo Technology: Calvin ends up making "medieval" flavored versions of 1990s technology.
 * Black Knight: He's a master jouster and gives to the people.
 * Blond Guys Are Evil: Inverted with Princess Sarah's two suitors as the nasty Lord Belasco is dark haired while the good Master Cane is blond.
 * Call Back: At the start Calvin's coach tells him to remember three things but then lists four things instead. When Calvin starts training with Master Cane, he says the same thing.
 * Chickification: See Faux Action Girl below.
 * Falling Chandelier of Doom: Lampshaded and subverted: The title character cuts the rope attached to a chandelier, but it doesn't fall, causing him to comment that "this always works in the movies". How the chandelier isn't falling even though its support is cut is never explained.
 * Faux Action Girl: The film provides us with a very ridiculous example of this trope with Princess Katie. In the training sequence she is shown to be an excellent swordswoman, archer and horse rider, thus she should be "of course, able to take care of herself". Except, then she gets kidnapped by some mooks, in broad daylight and needs to be rescued by Calvin and King Arthur. A fight begins. Now on the good guys' side we have Arthur (a very old man), Calvin (a nerd who fails at baseball and has only trained swordfighting for a couple of days) and Katie (who is young, fast and has trained swordfighting all her life). Arthur and Calvin fight and kill the mooks while Katie, who really should be "...able to take care of herself" gets kidnapped again.
 * The same film also subverts the trope, however, with Katie's older sister Princess Sarah. The viewer spends the entire movie believing that tomboyish Katie is the tough one of the pair, only to find out that
 * Groin Attack: Calvin gets one in while fighting.
 * Hair of Gold: Princess Sarah.
 * Idiot Ball: Once Arthur learns Belasco schemes to usurp the throne; rather than have Belasco thrown in the dungeon. Arthur lets Belasco go free until the tournament.
 * Obviously Evil: Lord Belasco. When a character is first introduced as the king's trusted and loyal adviser, and the very first shot of the movie that he's in shows him as a tall dark man with black robes, a black horse, black hair with white streaks, a sinister smile, and ominous background music, it's just insulting to our intelligence. He's like Jafar, except he's not hypnotizing the king, so the king really has no freaking excuse for trusting him.
 * Samus Is a Girl: is the Black Knight.
 * Save the Princess
 * Self-Proclaimed Knight: The master jouster Black Knight is revealed to be
 * That Poor Cat: When Calvin fires an arrow through a window by accident
 * Tomboy and Girly Girl: The two princesses.
