!The musical:
* ColbertBump: It's received a lot more attention lately after being revealed as the favorite musical (and movie) of Lewis Lovhaug, the host of the wildly popular ''WebVideo/AtopTheFourthWall'', with him citing the important role it played in forming his personal sense of morality as a child.
* CutSong: "Fie on Goodness" is cut from some productions. Another number, between Mordred and Morgan [=LeFey=], is often cut. Nobody misses it.
* SparedByTheAdaptation: King Pellinore, who [[spoiler: gets killed off half-way through Literature/TheOnceAndFutureKing]], survives until the end of the movie and is with Arthur in his final battle.

!For the TV Series:
* DuelingShows: ''Series/GameOfThrones'' and more loosely ''{{Series/Merlin}}''.
* StillbornFranchise: In the season finale, [[SequelHook the Round Table is established, and Mordred is conceived]]. Then the show was axed. The official reason was lead actors having prior commitments, but lower viewership and critical reception compared to contemporary shows like ''[[DuelingShows Game of Thrones]]'' didn't help.
