In her contract for this film, Natalie Wood required Warner Bros. to provide a portable trailer, white cigarette holders from London, oil gardenia from Cairo, days off when she was on her menstrual cycle, and a $160,000 salary.
While dressed in a woman's nightgown, Tony Curtis says he looks just like Jack Lemmon in the movie where he dresses up like a girl. Curtis and Lemmon co-starred in Quanto Mais Quente Melhor (1959), and both of them dressed like girls.
The four images on the wall in Natalie Wood's office that Tony Curtis looks at (Timidity, Repressed Hostility, Anxiety and Indecision) are by noted Russian illustrator Boris Artzybasheff.
Though his performance was one of the few that received praise, Henry Fonda later said that of all of the movies he'd made, he liked this one the least.
Tony Curtis, Natalie Wood, and Larry Storch would all go on to appear together in A Corrida do Século (1965) the following year, along with Jack Lemmon, who is frequently referenced in this picture.
