!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.

!For the TV Series:
* AwesomeDearBoy: Eva Green is a huge lover of witches and the occult, and loves the chance to play them.
* DuelingShows: ''Series/GameOfThrones'' and more loosely ''{{Series/Merlin}}''.
* FakeBrit:
** Eva Green once again downplays her French accent to play a British character.
** Peter Mooney, who plays Kay, is Canadian, as is Lara Jean Chorostecki (Bridget).
** Diramuid Murtagh (Brastias) is Irish.
* PlayingAgainstType: Claire Forlani was famous for various love interest roles in American films during the 90s. Playing a ProperLady in a fantasy piece is very different. What's more is that it's one of the first major roles where she gets to use her natural accent (she's English but normally plays Americans).
* 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.
