Trivia

  • The episode's title is a reference to a fictional book of the same name in the 1941 film Sullivan's Travels.
    • The title of this episode is from a Coens Brother 2000 film of the same name about the convicts who record a song in the depression era and become famous. The movie also draws a lot from the epic poem The Odyssey by Homer.
  • In the flashback at the beginning, Lex turned the sun red in a bid to de-power Superman, a reference to The War of the Superman storyline in 2010, when he briefly turned the sun red to save Earth from an invasion of hostile Kryptonians.
  • Lex's act of creating an earthquake is a reference to the original Superman (1978), where Luthor's master plan was to use the quake to sink the west coast and turn the near-worthless desert real estate he'd bought up into a valuable water-front property.
  • Lex having inoperable cancer after injecting himself with Kryptonite is a reference to the original comics, where he discovered that Kryptonite radiation was deadly to humans (if not quite so fast-acting as it is with Kryptonians) after he began wearing a Kryptonite ring to keep Superman at bay and later developed cancer.
  • Brainiac-5's contention that he usually gets along so well with machines may be a reference to his creation, in the DC comics, of COMPUTO, a sentient machine which became one of the greatest adversaries of the Legion of Super-Heroes.
  • While looking at a portrait of Lillian, Lex mentions how her eyes seem to follow one around, the same observation Mrs. Queller makes to Alex in "Shelter from the Storm".
  • It is implied Lena's mother was Irish, another nod to the former's actress, Katie McGrath, being Irish.

Goofs

  • There's a factual error in Lex's citation. Epicurus lived between 341–270 BC - making his statement over 2000 years old instead of ~280.
