While Tiffany Bolling was working on Wicked, Wicked, she was simultaneously making The Candy Snatchers (1973) at the same time.

Bolling did her own singing in Wicked, Wicked which may also explain why her aspirations for a singing career didn't pan out. She actually had a minor hit single with the Vietnam protest song, "Thank God the War Is Over," and even released an album called "Tiffany" which is now a collector's item.

"We picked Wicked, Wicked for the introduction of Duo-Vision for two reasons," Bare explains in the studio pressbook. "It is a suspense drama of the psycho-killer genre and the entire action is laid in an old seaside resort hotel. The plot and the setting combined beautifully to make our dual screens work. Although split screen sequences have been seen in the past and are still popular for such presentations as sports telecasts, Wicked, Wicked marks the first time that an entire movie has been filmed with parallel images," Bare says. "Although primarily it serves to depict simultaneous action," the director continues, "Duo-Vision also lends itself to showing truth and untruth, flashbacks in time, visions of the future or cause and effect without abrupt interruption of the story's main continuity. As applied to Wicked, Wicked the Duo-Vision technique involves an active screen and a passive screen, meaning that dialogue comes from only one screen at a time while silent footage unreels on the other so there is no dialogue confusion."
