The Miracle Worker is a 1979 American made-for-television biographical film based on the 1959 play of the same title by William Gibson, which originated as a 1957 broadcast of the television anthology series Playhouse 90. Gibson's original source material was The Story of My Life, the 1903 autobiography of Helen Keller. The play was adapted for the screen before, in 1962. The film is based on the life of Helen Keller and Annie Sullivan's struggles to teaching her. It starred Patty Duke (who played Helen Keller in the original 1962 film, for which she won the Oscar) as Annie Sullivan and Melissa Gilbert as Helen Keller. It produced a TV sequel, Helen Keller: The Miracle Continues in 1984. Source: Wikipedia (en)
