'''The film:'''
* BoxOfficeBomb: ''King Arthur'' failed to make up its $120 million budget in North America, only gaining just under $52 million. It fared considerably better worldwide, though.
* CreatorKiller: This movie was one of several 2004 bombs that mixed together with Roy E. Disney's second Save Disney campaign and general turmoil at the Walt Disney Company to bring CEO Michael Eisner's 21-year long reign to an end. Eisner was forced out the year after this film's release in order to allow president Bob Iger to keep Creator/{{Pixar}} when they threatened to jump ship.
* FollowTheLeader: Made after ''Film/{{Gladiator}}'' made SwordAndSandal films big again and the ''Film/LordOfTheRings'' film trilogy popularized MedievalEuropeanFantasy-style films. The film, set in 467 AD, straddles the two genres since it take place just a few years before the fall of Rome in 476 AD, which is usually considered the beginning of the MiddleAges.
* WhatCouldHaveBeen: The original ending of the film was replaced after test audiences thought it was too depressing. Instead of Arthur and Guinevere getting married and the knights who died getting reincarnated as horses, it shows the graves of the knights and a boy trying to pull out the sword from one's grave like Arthur once did. Arthur tells him that his time will come.
