So, I think Angie Harmon would have been a better fit for the role.
She did indeed have dark hair...but...that is what hair coloring is for! Honestly, though, I could not fault anyone for taking issue with my choices. I would say, though, that Dagny cannot be TOO good looking. She should have an angular, somewhat hard face, I would think. The kind of face that when other women see her in her executive role, they think she is a hard, sexless woman that men wouldn’t be attracted to (the same thought process Rearden’s wife, Lillian followed)
I have a darn hard time finding an angle at which Angie Harmon doesn’t look stunning...:)
Another choice for me would have been Helen Hunt.
