Hugo Haas's personal story and how it relates to this film is undeniably moving, but unfortunately the tale he created didn't have much of a spark to it, and if you're looking for noir you're probably barking up the wrong tree, this is a melodrama.
There is a certain pathos to the parallel stories involving acts of friendship which are accompanied by feelings, both in the rich woman (Mona Barrie) who sponsors the Czech pianist (Haas himself), and in his befriending the showgirl who's down on her luck (Cleo Moore). In both cases, it's the pianist who is the object of affection, but it's only with the younger women that he gradually begins to reciprocate. When she moves into his apartment, it's made clear he's like a grandfather to her, so that when they later marry we can be assured per the Production Code that their relationship was platonic beforehand, neutering what might have been wonderfully scandalous. The only flash of life for me was when she was swinging her hips in the kitchen, imagining her next musical number.
The film lumbers through the ensuing melodrama when unsurprisingly they don't just live happily ever after, but it all felt pretty staid, even the jealousy that develops when his career falters and she wants to return to work with a guy who looks like he's meant more to her than just a boss. This is one I liked seeing more because of Hugo Haas's life than the actual film, speaking of which, it was a nice touch to see his wife Maria Bibikov as Nurse Peterson towards the end.
