The script held in the Crawford Collection in the AFI Research Collection contains the following character notes (excluding regular characters):
'MICHAEL WALKER 20-ish. Major part. Student of art. Strongly attached to the past - to the old house where the family lived when his mother died - two old people and two children. He can't stomach the reality of life. Ever-present in the family's hamburger shop and the belching maleness of his old man - a phobia which grows to killing point.
'BEVERLEY WALKER 22-23. Major part. Michael's sister. She is protective towards him partially taking the place of the dead mother. Not a pretty girl, she will probably end up an old maid, having sympathy, able to be deeply hurt, loyal to her family against outsiders.
'BILL WALKER 45-ish. The father. Must be burly, excessively male, offensively coarse and over-friendly rather than ill-tempered. Dies at first commercial.
'ALICE THOMSON 40-ish. Helps in the hamburger shop. Fond of Bill Walker as much as she can be fond of anyone. Mostly concerned for herself. Amoral, thoughtless, deceptive, sharp-tongued. Certain that she and her type keep the world going round.
'JOE SAUNDERS 40-ish. Alice Thomson is his de-facto. A criminal mind, low intelligence. Likes to play the part of a cheeky, likeable crim, but in fact is a brutal unimaginative 40-year 'old [sic] boy whose taste for the bash, booze and birds has never changed.
'FREDDY HALL Mid-20's. Able to drive. A tough cheeky little character with plenty of guts and a broad streak of humour.
[Regular characters omitted]
'POLICE DOCTOR One scene with dialogue. A firm confident manner.
'CONSTABLE Extra.
'JOHN JENKINS 20-ish. Able to drive. Freddy Hall's mate probably because Hall feels sorry for him. Overweight, cowardly. Dobs everybody in every time he's threatened. Should have been born a girl not a boy.
'MOTOR CYCLE PATROL MAN Fast motor-bike chase.
'MEAT DELIVERY MAN Burly like Bill Walker. Carries meat into butcher's shop.
'TAXI DRIVER Little, dark, puzzled foreigner. Drives.
'TEENAGE BOY AND TEENAGE GIRL Extras. To be served in the shop.
'OLD MAN One scene only. Extras. Enters shop.
'2 DEMOLITION WORKERS Able to swing sledge hammers.
'VARIOUS EXTRAS Onlookers at scene of arrest.'
