The document discusses casting and costume choices for two main characters, Character A and The Friend, in a film. Bella Rix was cast as Character A because of her experience with complex emotions from drama studies. Mabel Collins was cast as The Friend because she is talented at playing innocent roles and has an innocent appearance. Character A will wear worn, dark clothes to portray mystery and mental deterioration, while The Friend will wear pale colors to seem innocent. A realistic toy gun and Character A's bike will also be used as props.
