Title: Georgia (1995 film)
Passage: Georgia is a 1995 American independent film starring Jennifer Jason Leigh and Mare Winningham.  In the film, Leigh played Sadie Flood, a punky barroom singer who has a complicated, jealous but loving relationship with her older sister, Georgia, played by Winningham.  Georgia is a successful, talented and well-adjusted folk music singer and a happily married mother of two.  Sadie is passionate but self-destructive and untalented.  While she seeks fame, she destroys herself through drug abuse.  Although the movie focuses largely on Sadie, it was apparently titled "Georgia" because Sadie defines her own identity so much through her older sister.
