Pop culture buffs have noted that three cast members, Frank Gorshin (The Riddler), Burgess Meredith (The Penguin) and Cesar Romero (The Joker), played recurring villains in the 1966–68 "Batman" television series, which broadcast its final episode in March, nine months before "Skidoos release. The film's then-futuristic costume designer, Rudi Gernreich, also made an acting appearance on "Batman" and, in one 1966 two-part episode, Otto Preminger, himself, portrayed another of the show's recurring villains, Mr. Freeze (in the character's first appearance on the show, he was played by George Sanders and, when seen for the third time, by Eli Wallach).
