I like Greer Garson as Marie Curie. I liked both Deborah Kerr and Irene Dunne as Anna and the King of Siam. Dont’ forget Debbie Reynolds as the unsinkable Molly Brown
I have dim memories of Marie Curie and The King and I. I never saw Debbie Reynolds.
I want to mention Candice Bergen in The Wind and The Lion. That is one of my favorite films of all time. It is an action adventure movie, but instead of the good guys against the bad guys, it is the audacious against the wimps.
