A screenplay, also known as a script, is a written work by screenwriters for a film, television show, or video game. It is a form of narration in which the movements, actions, expressions, and dialogue of the characters are described in a certain format. Screenplays can be original works or adaptations from existing pieces of writing. A screenplay is the blueprint for a final product, and it includes the dialogue of all characters, their movements, place setting descriptions, and acting style indications. Visual or cinematographic cues may also be given, as well as scene descriptions and scene changes. A screenplay is different from a script, which is a generic, broad term that can refer to any written work for film, television, or video game.
