The script held in the Crawford Collection in the AFI Research Collection includes the following character notes:
'BEVERLY JONES. Late forties. An ex-nurse. Hard, disillusioned. Drives.
'SID WALKER. A few years younger. Her de facto husband. Unscrupulous. He is afraid of physical violence, but brave as long as he is faced with someone weaker than himself. Drives.
'KIRSTY ANDERSON. 16 years old. Still goes to school: the Convent. She has fallen for Cliff because he in handsome, and because she is old enough now to be in love. The events of the story make her grow up.
'CLIFF WELLS. Mid-twenties. Good looking. Thought Kirsty a sweet kid, nice to have a good time with. He sees abortion as the obvious answer to an unwanted pregnancy. Drives.
'AILEEN MILLER. Late twenties or early thirties. Unhappily married. Did not want another child because her husband drinks heavily and then becomes violent towards her and her son. Drives a car.
'DOUG MILLER. Mid-thirties. Filled with resentment towards his wife and child because he thinks they have forced him to abandon a colourful career. He drinks.
'TOMMY MILLER: Seven year old boy. Should be small for his age. He has the air of a grown-up like many children who live in constant fear.
'DR. KAREN BROWN A doctor at the Matlock hospital. She believes in abortion-law reform; she is slightly defiant towards Maddern, though she considers him to be more human than most police.
'NATALIE. Hairdresser who arranges abortions.
'MRS. CARTINI. A middle-aged migrant woman. Completely out of her depth: she does not speak English well, knows only one thing: it is a sin to have an abortion. Yet she is willing to commit it because she can't face having another child.
'O'NEIL. A log-contractor. Likeable, helpful. (Strong build, outdoor type essential).'
