Gilda feels a lot like Casablanca, except with a happy ending—which wouldn't have worked well even if it hadn't already been done in To Have and Have Not (a film that at least had Bogie). Similar to Casablanca, Gilda centers on a love triangle unfolding within a gambling establishment set in an unusual locale. While Casablanca is situated in North Africa during wartime, this one takes place in South America shortly after the war. Furthermore, where Casablanca concludes with “the beginning of a beautiful friendship,” Gilda wraps up with the continuation of a difficult romance. Following the pattern established by Rick Blaine, Ilsa Lund, and Victor Lazlo, Johnny Farrell is living an easygoing life running a casino in Buenos Aires when Gilda reappears alongside Ballin Mundson. Macready’s character has an unfortunate name—Victor Lazlo sounds merely foreign, but Ballin Mundson seems almost otherworldly—and Hayworth certainly fits her role; Ford, meanwhile, was taller than Bogie, though there's a considerable difference between height and presence. Gilda married Ballin after knowing him for only one day, which drives Johnny wild with jealousy. However, to Gilda’s dismay, he’s less jealous of Ballin than he is of her—and that’s understandable; casino owner Ballin serves as something of a mentor and father figure to Johnny, who acts as his bodyguard, confidant, and right-hand man. Essentially, Ballin is betrayed by Gilda with Johnny's involvement, although Johnny more to protect Ballin than to assist her. The entire story is twisted and enjoyable thanks to Hayworth; Johnny hates her intensely, and if we never question the genuineness or strength of this feeling, it’s not Ford’s acting but hers that makes us believe in Johnny's hatred—and even share it. Like Bette Davis in Of Human Bondage, Hayworth owes her deserved recognition to a truly notorious character. The distinction is that Leslie Howard ultimately triumphs, unlike Scott Pilgrim or The Power of Self-Respect; Johnny, however, not only places the woman on a pedestal but keeps her there. He pleads with Gilda: “I want to go with you … Please take me,” and has the luck, or perhaps misfortune, of Gilda welcoming him back with open arms, justifying this decision with questionable reasoning that "No one needs to apologize because we were both scoundrels, right? Isn’t it wonderful?". All things considered, some couples will always have Paris; for others, there's always Family Court.
