"Driving Miss Daisy" is a 1989 American comedy-drama film directed by Bruce Beresford and written by Alfred Uhry, based on Uhry's 1987 play of the same name. The film stars Jessica Tandy, Morgan Freeman, and Dan Aykroyd. Freeman reprised his role from the original Off-Broadway production.

The story defines Daisy and her point of view through a network of relationships and emotions by focusing on her home life, synagogue, friends, family, fears, and concerns over a twenty-five-year period.

In 1948, Daisy Werthan, or Miss Daisy (Jessica Tandy), a 72-year-old wealthy, Jewish, widowed, retired schoolteacher, lives alone in Atlanta, Georgia, except for a black housekeeper, Idella (Esther Rolle). When Miss Daisy drives her 1946 Chrysler Windsor into her neighbor's yard, her 40-year-old son Boolie (Dan Aykroyd) buys her a 1949 Hudson Commodore and hires Hoke Colburn (Morgan Freeman), a black chauffeur. Miss Daisy at first refuses to let anyone else drive her, but gradually accedes to the arrangement.
