The script held in the Crawford Collection in the AFI Research Collection contains the following character notes (excluding regular characters):
'SIDNEY ROBERTS Late forties, a professional criminal. A hard man, self-confident. His only weakness is his wife Elsie. He genuinely loves her and the only time we see a softness in him is when he is with her.
'ELSIE ROBERTS Forties. A weak, silly woman. Roberts is and always has been her life. She recognises only the good side of him and takes the attitude that if she ignores the bad things about him they haven't happened. She is a very devout catholic [sic] lady.
'MRS. ARCHER Sixties. A very forceful character with an old-fashioned set of values. She owns the flats Elsie lives in and also lives next door to her.
'CAROL ARCHER A swinging 17. The grand-daughter.
'ERN FULLER Forties. A criminal. Not very smart, rough.
'SISTER IGNATIUS An elderly nun. A very slight, Irish brogue that comes out occasionally when she speaks about home. Must be approximately the same size as Roberts.
'AMBULANCE ATTENDANTS Two.
'"MUMMA" WALSH Forties. A fat jovial character. He loves cooking and looks as though he enjoys eating.
'BENNY ADAMS Same age group. A petty criminal, now reformed.
'PERCY McCALL Fairly old. A seedy little man.
'BOB STEIN Carol Archer's boyfriend. Perhaps 20. A nice boy, not quite as swinging as Carol.
'DOUG MARTIN Detective.
'DRIVER Another policeman.
'CAPTAIN AND CREW OF SHIP Actual.
'POLICE CONST.'
The final character, 'Police constable', has been added to the bottom of the list in blue ink. The names of actors are written under each character on the list in blue ink, except for the characters Bob Stein and Doug Martin.
