- This episode had a visual error: in a close-up Spock had normal eyebrows.
(Picture showing this error, 32KB jpeg).
- The aliens in "The Eye of the Beholder" would have been impossible to do in a live action series.
- Another small error in the episode: Lieutenant Commander Tom Markel was shown with Commander stripes.
- In this episode, a purple flying lizard-like creature menaced members of an
Enterprise landing party. The animated
sequence made use of drawings originally created for the flying plant creatures that menaced the
Enterprise landing party in "The Infinite Vulcan".
Another example of similar life forms evolving on different planets.
- There was a seventh season
STAR TREK: The Next Generation episode
"Eye of the Beholder",
and also a classic Twilight Zone episode by that name.

but it is an entirely different story.
- Another visual error: the crew of the U.S.S. Ariel wore the insignia of the
Enterprise. (Bjo Trimble's 1976 Concordance conjectured that the insignia of the Ariel
was an elongated and more angular arrowhead design than the Enterprise insignia.)
