This is the original of Young at Heart, which I commented on earlier. The ending had the potential of being truly tragic, but was vitiated by having a second marriage. I preferred the 1950’s version in which Doris Day slowly comes to the realization that Sinatra’s character was her true love. Worth seeing, but stop watching after the hospital scene.
The ending of Young at Heart, it should be noted, wasn’t tragic, and it would have been more satisfying if things were left hanging, or if Sinatra’s character had died, but it was more sentimentally satisfying to end it as they did, then the wretched ending of Four Daughters.
