While making this film on location, Doris Day repeatedly complained to her husband Martin Melcher, whose first film as a producer this was, that she felt ill and needed a rest. He insisted that she adhere to her Christian Science beliefs - and the film's shooting schedule - and "have faith" that whatever was ailing her would pass. Once shooting was completed, Day consulted her doctor in Beverly Hills, and discovered a large ovarian tumor, which required her to have a hysterectomy.
While in pre-production for this film, Doris Day was being driven to a local airport to learn some airplane cockpit tips when the car she was riding in was slammed into by a teenage hot-rodder. Despite the potential seriousness of the situation, nobody was hurt and Doris writes that she remained remarkably unfazed by the accident.
