I think that Jeannette McDonald would have been a longer box office draw because she could portraya evolving woman in movies Nelson Eddystruck me as an actor unable to change or evolve to the movie goers perception of a modern man. I have seen McDonal in a couple of films other then her usual parings with Nelson Eddy. As society became more open and accepting of changing social norms,I think. McDonald and Eddy seemed stintedand emotionally devoid of modern morality.
