Neill Rea's portrayal of Arthur as whiny and belligerent, but not wholly unsympathetic, appears to be heavily influenced by Graham Chapman's version of the same character in Monty Python and the Holy Grail (1975), a film which appears to be a prime influence on the Xenaverse overall. There are other subtle "quotes" of that film in the episode, such as Arthur's obsession with being proclaimed king by the Lady of the Lake, and the scene where the Black Knight arrives.
Score from a previous episode, is tracked in.
