The character of Daniel Mockridge would later make a cameo appearance in Batman: Mask of the Phantasm (1993).
When Edward Nygma is doing a crossword one of the words appearing is Radomski which is the last name of the director of this episode Eric Radomski.
First appearance of the Riddler. His costume is a simpler version of an alternative costume that Frank Gorshin requested during the production of Batman (1966) since he did not like the character's unitard costume. Since the introduction of this version of the character, the Riddler in the comics has largely abandoned his original costume for that green business suit and bowler hat look ever since.
The computer game which is at the heart of this episode is based on Greek mythology. According to legend, King Minos had a monster, the half-man/half-bull known as the "Minotaur" and he commissioned Greece's greatest genius, Daedelus, to build a labyrinth in which to keep it.
Some of the sound effects heard in the Riddle of the Minotaur game are very similar to the Super Mario Bros series of video games.
