In watching this movie for the first time in almost 40 years, I found myself wondering why I liked it the first time around and again in re-watching. Joan Crawford was undoubtedly a "star" in the truest sense of the word; in the special features, William Castle and Diane Baker both confirm the many demands and conditions Ms. Crawford placed on the film. Her performance is definitely camp, but watching her play someone yearning for her youth, it hit home how Crawford's real life was shaping into the fall of a movie goddess.
But in the film, notice the strength Crawford and Baker give in their reunion. Without a word, the two actresses strongly display the range of emotions they are both feeling.
Diane Baker, who unlike one reviewer mentioned, had to this point played the innocent young ingenue, e.g. Best of Everything, Journey to the Center of the Earth, and in this one, she capitalizes on this innocence, so that when the venom comes, it's quite a transition. Seeing a young Lee Majors in his pre Big Valley days just reminds me how much time has elapsed!
Castle's films were gawdy, manipulative, but above all, they were entertaining.
Joan Crawford and Diane Baker are to be commended for rising above the inevitable and making this a classic camp film.
