The property master, often called the prop(s) master, is an artistic and organizational employee in a film, television or theatrical production who is responsible for purchasing, acquiring, manufacturing, properly placing, and/or overseeing any props needed for a production. The property master also works with other members of the production managing the physical appearance of the stage or set; for example, they might work with the script supervisor to maintain set continuity. The property master is on staff during preproduction, develops the stylistic concept of the physical production, then continues on as a member of the physical shooting/production crew. A person responsible for purchasing the props can be called a props buyer or production buyer.
