According to Janet Leigh, she, Curtis and Martin had the time of their lives making Who Was That Lady?. "This was a romp from start to finish; I hope the audience had as much fun as we did," she says in her 1984 autobiography There Really Was a Hollywood. "We really rolled with this one. The personal familiarity of the three of us allowed absolute freedom, and the interplay was wild and woolly and inventive." There was an atmosphere of playfulness on the set that lent itself to practical jokes, attempts to make each other laugh in the middle of takes, and escalating water fights. "...it started innocently and quietly," Leigh explains about the water fights in her book. "A paper cup here, a flick there. It grew to water guns, first casually, then ambush. We would wait on top of our dressing rooms for one unsuspecting victim to return from lunch or the restroom and attacked from above with one or two weapons." via TCM
