A script is a written document containing dialogue, stage directions, and other instructions for actors, directors, and production crews in theater, film, television, or other media productions. It serves as a blueprint for bringing a story to life, detailing character interactions, settings, and narrative progression. Scripts vary in format depending on the medium and may include scene descriptions, character motivations, and technical cues. They undergo revisions and edits throughout the production process, ensuring coherence and alignment with the creative vision.
