All of the people on the yacht robbed by Mr. Freeze are based on the characters from "Gilligan's Island".
Clancy Brown, voice of Mr. Freeze/Victor Fries played 'The Kurgan' in Highlander (1986). We are treated to a one-line nod to Highlander here when Freeze says the line "Another Time, then, Batman", just as the Kurgan proclaimed to Connor upon their first meeting and separation; "Another time, Highlander!"
The name of the boat from the opening screen is Olympia which was the sister ship of the Titanic.
DEBUT: Victor Fries/Mr. Freeze (episode 1.06 "The Big Chill")
The title was spoken by Mr. Freeze during his first encounter with Batman.
