The film’s intriguing premise provides just enough momentum to carry it through its nearly two-hour length. Jean Simmons, as "Mary," expresses deep dissatisfaction with her marriage to "Fred" (John Forsythe), and after attempting to find stimulation through alcohol and drugs, she runs away to the Bahamas – even pawning her watch to finance the trip on their wedding anniversary. It's during this flight that she meets an old friend, "Flo" (Shirley Jones), and her companion, "Sam" (Lloyd Bridges), who then take charge of the now impoverished "Mary." She soon begins to realize that things aren’t always better elsewhere, but her time in this beautiful place allows her to reassess what's important and how she views herself, as well as comparing her life with those around her. Simmons evoked a bit of Liz Taylor while watching; she conveys a sense of assurance when portraying a middle-aged woman wrestling with inner turmoil—someone who is imperfect, jealous, yet also kind and isolated. Jones delivers a solid performance too, playing the role of a friend whose life seems to consist mainly of relationships with wealthy men who offer amusement and extravagance but little real meaning. Bobby Darin, as "Franco," ultimately helps her understand things more clearly. The film unfortunately spends too much time on Fred’s perspective, because Forsythe didn't bring enough depth to the role. He certainly possessed charm and a certain elegance, but even at his most emotionally charged moments in the movie, his portrayal of a devoted husband felt more like that of a concerned physician. There was nothing genuinely intense about his acting, and I believe this significantly diminished the film’s overall quality. Lloyd Bridges isn't one of my favorite actors either, and here he doesn’t add much by way of contrast to Jones’s pleasant but self-centered character. There's plenty to engage with, thanks to a compelling story (though I didn’t care for the conclusion) and direction that matched the star’s style. The dialogue is lengthy and occasionally overly dramatic, but it still provides an opportunity for Jean Simmons admirers to enjoy her performance. It had the potential to be much stronger, though.
