I like Dennis Morgan but...
he really can't carry this movie. He has a nice voice and is a likable actor, but he does better in movies with a strong leading lady for him to bounce off of - like Barbara Stanwyck or Ginger Rogers.
Here he is the main "name" with Andra King and Arlene Dahl as his unremarkable female co-stars. He has the same expression and demeanor basically through the whole movie.
