I'm curious why they changed out the actors from Part I to Part II. My wife & I are very partial to Dagny Taggart from Part I. She seemed to most closely resemble the character in the novel. She was much more believable and looked like the true character description, piercing eyes and determination while still being an elegant and attractive lady entrepreneur. I guess they couldn't get the same actress lined up for the role due to contract payment request or unavailability.
