Ginger Rogers
I can see why Ginger Rogers went from this film to a brilliant career. It showcased her movement/dancing talent, as well as her comedic timing and dramatic ability.
Two of my favorite lines, complete with the accompanying movements, are:
--"Now, if you'll excuse me, I think that I shall take the wolf-hounds for a stroll."
--(To Adolph Menjou's inquiry about rehearsing a dance): "No, we're just getting over the DT's."
