The film features a homogeneous cast within a localized British context. There is no indication of a multi-ethnic cast or non-white characters.

The narrative explores subjective morality by centering on characters who bypass legal institutions. It depicts how wartime trauma can drive anti-social behavior.

The characters suffer from psychological trauma following the Second World War. However, this trauma serves the plot rather than offering a nuanced study of disability.
