I love Jeanette MacDonald/Nelson Eddy movies too! And Sonja Henie's a delight too! Ironically as my avatar has been Alice Faye for all these years, I haven't seen that many of her movies (and the ones I have were many years ago).
I purchased 3 Ann Harding movies in the holidays, as I can now purchase from Amazon USA again !!! (so excited !)
I bought, Her Private Affair, Double Harness and The Animal Kingdom.
Have watched the first, thoroughly enjoyed. I was mesmerised by Ann Harding. So beautiful. And a great actress in this her fist movie I believe it was (from 1930?)
