Fifty years ago this year, on Jan. 31, 1974, CBS premiered a film adaptation of “The Autobiography of Miss Jane Pittman,” which became the most-watched television movie in history. The production, which told the story of a 110-year-old woman who’s born into slavery and lives long enough to witness the Civil Rights Movement, was based on the bestselling 1971 novel by Pointe Coupee Parish native Ernest J. Gaines. Filmed in and around Baton Rouge, the CBS project won nine Emmys.
