Unseen character

An unseen character or invisible character is a fictional character referred to but never directly observed by the audience. They are characters that are "heard of, but never heard from". They are continuing characters—characters who frequently interact with the other characters and who influence current story events.

The significance in the plot excludes from this definition various occasional barely mentioned characters, such as Laurent (Lawrence), Tartuffe's unseen valet, whose sole function is merely to introduce the pompousness of Tartuffe, as seen from his very first words of the play; see Scene II.

Unseen characters are a common device in drama. Books can feature characters who are referenced by others, but whose actions and dialogue are never directly described. The work of Voltaire, for example, included the "unseen character".

Theatre

 * Rosaline in William Shakespeare's Romeo and Juliet is never seen, but is crucial to how the title characters meet.
 * In Alain-René Lesage's 1707 play Crispin an unseen character called Damis with his forced secret marriage is essential to the whole plot.
 * In Clare Boothe Luce's play The Women (1936), and the 1939 film based on the play, male characters (husbands, lovers, etc) are referred to but do not appear, even in photographs, and the entire cast (from stars to extras) is all female.
 * Godot in Samuel Beckett's Waiting for Godot is never seen. The play's two main characters spend the entire play waiting for Godot to arrive.

 * Minder: Arthur Daley's wife, referred to only as "'Er Indoors", is never seen or heard, but often quoted.
 * I'm Sorry I Haven't a Clue: the scorers Samantha (or occasionally Sven) are regularly referred to but never appear. An empty chair is provided for them at recordings.
 * In the long-running British radio soap opera The Archers, a number of permanent inhabitants of the village in which the story is set are frequently referred to by name but are never heard from in their own voices. Fans of the programme often refer to these characters as "the silents".
