composite character based on the novels of Tolstoy and Dostoevsky. Annie Hall was very important in Allen's and Keaton's careers. It is said that the role was written for her, as Keaton's birth name was Diane Hall. She then starred in Interiors as a poet, followed by Manhattan. In 1987, she had a cameo as a nightclub singer in Radio Days, and she was chosen to replace Mia Farrow in Manhattan Murder Mystery after Allen and Farrow began having problems with their relationship. In total Keaton has starred in eight of Allen's films. As of 2018 Keaton and Allen remain close friends. In a rare public appearance, Allen presented Keaton with the AFI Life Achievement Award in 2017. Mia Farrow Allen and Mia Farrow met in 1979 and began a relationship in 1980; Farrow starred in 13 of Allen's films from 1982 to 1992. Throughout the relationship they lived in separate apartments on opposite sides of Central Park in Manhattan. Farrow had seven children when they met: three biological sons from her marriage to composer André Previn, three adopted girls (two Vietnamese and one South Korean, Soon-Yi Previn), and an adopted South Korean boy, Moses Farrow. In 1984, she and Allen tried to conceive a child together; Allen agreed to this on the understanding that he need not be involved in the child's care. When the effort failed, Farrow adopted a baby girl, Dylan Farrow, in July 1985. Allen was not involved in the adoption, but when Dylan arrived he assumed a parental role toward her and began spending more time in Farrow's home. On December 19, 1987, Farrow gave birth to their son Satchel Farrow (later known as Ronan Farrow). According to Allen, his intimate relationship with Mia Farrow ceased completely after Satchel's birth and he was asked to return her apartment key; they maintained a working relationship when they filmed a movie, and he regularly visited Moses, Dylan and Satchel, but he and Mia were only "social companions on those occasions where there'd be a dinner, an event, but after the event she'd go home and I'd go home." In 1991, Farrow wanted to adopt another child. According to a 1993 custody hearing, Allen told her he would not object to another adoption so long as she would agree to his adoption of Dylan and Moses; that adoption was finalized in December 1991.
