A prop, formally known as (theatrical) property, is an object used on stage or on screen by actors during a performance or screen production. In practical terms, a prop is considered to be anything movable or portable on a stage or a set, distinct from the actors, scenery, costumes, and electrical equipment. Consumable food items appearing in the production are also considered props
The term has readily transferred to television, motion picture and video game production, where they are commonly referred to by the phrase movie prop, film prop or simply prop. In recent years, the increasing popularity of movie memorabilia (a broader term that also includes costumes) has added new meaning to the term “prop”, broadening its existence to include a valuable after-life as a prized collector’s item. Typically not available until after a film’s premiere, movie props appearing on-screen are called “screen-used”, and can fetch thousands of dollars in online auctions and charity benefits.
