Gilda is just like Casablanca if Casablanca had a happy ending, which would have been a bad idea even if it hadn’t been already done two years earlier in To Have and Have Not (which at least had Bogie in it).
Like Casablanca, Gilda revolves around a love triangle set in a gambling establishment in an exotic location, but while Casablanca takes place in North Africa during World War II, Gilda takes place in South America just after the war. Moreover, if Casablanca ends with "the beginning of a beautiful friendship", Gilda concludes with the continuation of a horrible romance.
