The New York Times critic noted in his review of this film on May 27, 1967, that "of all the witty demonstrations, one of the most amusing" in the film was when Jayne Mansfield loses her bra in the home of Terry-Thomas. The sex symbol's two-minute cameo was shot under great personal distress, however. Filmed in mid December 1966, at the time Zoltan Hargitay, Mansfield's youngest son with Mickey Hargitay, was recovering from spinal meningitis at Conejo Valley, California Community Hospital, after undergoing brain surgery resulting from his being mauled by a lion in a freak accident at the Jungleland Park in Thousand Oaks, California, on November 26, 1966. Zoltan spent exactly one month in the hospital, returning home to Jayne's "Pink Palace" on that year's Christmas morning. Though several Mansfield films were released after her untimely death six months later, the scenes in this one were, as an actress, her final moments before the professional movie cameras.
Each celebrity who did a cameo was paid $10,000 for two days work (including The Turtles, who sang the title song). If anyone was required to work for more than two days, they were to receive an extra $10,000. No one went overtime.
Before this movie, Phil Silvers, Terry-Thomas, and Sid Caesar, who were credited as technical advisors on this movie, appeared in It's a Mad Mad Mad Mad World (1963).
