Letter From an Unknown Woman or The Constant Nymph
The two movies are common in one aspect: They both feature a young girl loving a musician. As the young girl gets older, she still loves the musician. Of course, the actress was the same - Joan Fontaine.
Although "Nymph" is very good, "Letter" is great. Why? I'm not sure. Perhaps it's because Joan played a young girl of 14 better in "Letter." This is, even though, she was five years older. Later she played a girl of 19 or 20 also better. Of course, she played the older beautiful woman to perfection in "Letter." In "Nymph," she never played the older woman because her character had died. For some reason, she was much prettier as a 19 or 20 year old in "Letter" than in "Nymph."
The director in "Letter" was Max Ophuls and he did a better job, imo, than Edmund Goulding in "Nymph."
So, obviously, I pick "Letter From an Unknown Woman." Any thoughts?
