Calista Kay Flockhart (born November 11, 1964) is an American actress who is primarily recognized for her work in television. She is best known for playing the title character in the Fox comedy-drama series Ally McBeal (1997–2002) for which she won a Golden Globe Award. She currently stars as Sally Field’s character’s daughter, Kitty Walker McCallister, on the ABC drama, Brothers & Sisters.
In spring 1989, Flockhart made her first television appearance in a minor role in an episode of Guiding Light as a babysitter. She made her professional debut on the New York stage, appearing in Beside Herself alongside Melissa Joan Hart, at the Circle Repertory Theatre. Two years later, Flockhart appeared in the television movie Darrow. Though she later appeared in films Naked in New York (1993) and Getting In (1994), her first substantial speaking part in a film was in Quiz Show, directed by Robert Redford.
Throughout her professional career, Flockhart has maintained her naturally lean figure. However, many have commented that Flockhart had become dangerously thin, particularly when the actress made red carpet appearances in clothing that revealed a somewhat emaciated physique. She had maintained throughout the show's run that she was never diagnosed with either anorexia or bulimia, nor was she a user of illegal drugs. She did remark, however, that while starring in the show she refrained from eating sweets, retaining her slimness with intense workouts and running.
