In a lesser film, Dorothy would be a simple love interest. Zellweger makes her the moral center of the universe. She is quiet, observant, and brave. Her decision to leave a stable job for a man with a "vision" is the film’s most radical act of faith. Zellweger’s ability to convey lifetimes of emotion with a simple glance (the “You had me at ‘hello’” take) is acting masterclass.
