- Colbert Bump: 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 Atop the Fourth Wall, with him citing the important role it played in forming his personal sense of morality as a child.
- Cut Song: "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:
- Awesome, Dear Boy: Eva Green is a huge lover of witches and the occult, and loves the chance to play them.
- Dueling Shows: Game of Thrones and more loosely Merlin.
- Fake Brit: Eva Green once again downplays her French accent to play a British character.
- Stillborn Franchise: In the season finale, 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 Game of Thrones didn't help.
