I know, I think I had heard that before as well. And I remember my mother always saying that Ginger was not Fred's best partner. Ginger got her share of grief as not being all that great, were it not for Fred. I don't know what the Hollywood studio politics were at the time, but an Astaire-Rogers aficionado or historian would sure know what the general attitude was regarding who would have been the perfect partner for Astaire. Rogers was plenty good in my book, though it is probably easy to argue that there surely had to be better dancers in her time. But were they better actresses or would their chemistry be perfect for Fred? I think Rogers hits high marks in those areas.
You know, I can't say that I remember Astaire voicing an opinion about her, but he surely must have. This is one of those areas that I can say I am a little bit too young to know all of the ins and outs of America's great dance couple.
