The script held in the Crawford Collection in the AFI Research Collection contains the following character notes (excluding regular characters):
'CHRIS CLARK: She's a real charmer. Attractive, intelligent, doing her Doctorate in Psychology at Uni; but not the type to shove her academic achievements down your throat. It's the same with her wealth - she wears it easily and well. She's as happily unselfconscious in her denim gear as she is in her Mercedes. We should feel that if a relationship were to develop between her and Redford, it would be great for both of them. About 24 years old.
'JOHN CLARK: Like Chris, he's an attractive character - perhaps a little old in his ways and conservative in his dress for his age (23) ... but it's an appealing fault. It stems from his admiration of, and desire to emulate his father. He's extremely proud to be his father's business partner - and anxious to prove himself worthy of the honour.
'JUDITH CLARK: About 48. As with the other members of the family, she's been shaped, in part, by Charles Clark. She's quiet, conservative, poised. Well matched to her immaculate and expensive home ... everything in good taste.
'CHARLES CLARK: He dies in the teaser but has a major impact throughout the story. He's a wealthy man and knows how to spend his money. We like the Charles Clark we first meet - if only because he's so obviously fond of his family; and has a good relationship with them. Early 50's.
'CARETAKER (MR. FAY): A nervous little man in a big lumbering body. Thick, surly, scared, uncooperative - all in all, not a very attractive personality. Should be a good colourful character.
'JACK KELLY: Mid-30's, drives - needs to be reasonably physical. Graduated from bouncer to manager of a massage parlour; and from there to blackmail. He's found his niche in life.
'GIRL: At the massage parlour. Extremely attractive - and appealing.
'DAVE (BOMB EXPERT): Has the confidence that comes from the knowledge that he does his job well. Happy to treat a police inspector as an equal.
'TONY VELLA: A delinquent kid, about 20. There's no doubt he's a thug and he'll probably spend half his life in gaol, but he's not without charm. Has a grudging respect for Redford.'
