The script held in the Crawford Collection in the AFI Research Collection contains the following character notes (excluding regular characters):
'CLIFF WEBB In early 30's. Boastful, unscrupulous, unfeeling, vicious. Was crack shot in Army, and in overseas service had got used to roughing it. Mad about guns. Driver.
'VALERIE WEBB His estranged wife, about 30. A decent girl who put up with Webb's harsh treatment and womanising for years for the sake of their two children. She recently left him, and works in fruiterer's shop to maintain the children.
'JACK DELANEY About 40. Accomplice of Webb and Tommy Fraser when they rob a store. Outwardly bold and tough, he is really weak, cowardly and complaining -- and the first of the three men to crack.
'TOMMY FRASER Valerie's brother, about 20. Has hero-worshipped Webb since he was a small boy listening to boastful accounts of his exploits. Follows Webb into crime because he makes it seem adventurous.
