Unseen character

An unseen character in theatre, comics, film, or television, or silent character in radio or literature, is a character that is mentioned but not directly known to the audience, but who advances the action of the plot in a significant way, and whose absence enhances their effect on the plot.

History
Unseen characters have been used since the beginning of theatre with the ancient Greek tragedians, such as Laius in Sophocles' Oedipus Rex and Jason's bride in Euripides' Medea, and continued into Elizabethan theatre with examples such as Rosaline in Shakespeare's Romeo and Juliet. However, it was the early twentieth-century European playwrights Strindberg, Ibsen, and Chekhov who fully developed the dramatic potential of the unseen character. Eugene O'Neill was influenced by his European contemporaries and established the absent character as an aspect of character, narrative, and stagecraft in American theatre.

Purpose and characteristics
Unseen characters are causal figures included in dramatic works to motivate the onstage characters to a certain course of action and advance the plot, but their presence is unnecessary. Indeed, their absence makes them appear more powerful because they are only known by inference. The use of an unseen character "take[s] advantage of one of the simplest but most powerful theatrical devices: the manner in which verbal references can make an offstage character extraordinarily real [...] to an audience," exploiting the audience's tendency to create visual images of imaginary characters in their mind.

In a study of 18th-century French comedy, F. C. Green suggests that an "invisible character" can be defined as one who, though not seen, "influences the action of the play". This definition, according to Green, would rule out a character like Laurent (Lawrence), Tartuffe's unseen valet, whose sole function is merely to give the playwright an opportunity to introduce Tartuffe.

Unseen characters can develop organically even when their creators initially did not expect to keep them as unseen, especially in episodic works like television series. For instance, the producers of Frasier initially did not want to make the character Niles Crane's wife Maris an unseen character because they did not want to draw parallels to Vera, Norm Peterson's wife on Cheers, of which Frasier was a spin off. They originally intended that Maris would appear after several episodes, but were enjoying writing excuses for her absence so eventually it was decided she would remain unseen, and after the increasingly eccentric characteristics ascribed to her, no real actress could realistically portray her.

Literature

 * Sauron, the eponymous arch-villain of The Lord of the Rings, remains within his fortress of Barad-Dûr and does not speak or make any physical appearance during the trilogy. His presence in the story is thus effectively more like that of a force of nature than that of an individualised personality, giving him a gravitas that inspires awe and dread both in the reader and in the characters, even when they are physically far away from Barad-Dûr. For example, as Frodo approaches the gates of Mordor, Sauron's spiritual presence and power is described as follows: "Frodo knew just where the present habitation and heart of that will now was: as certainly as a man can tell the direction of the sun with his eyes shut. He was facing it, and its potency beat upon his brow".

Comics

 * Al Capp introduced Lena the Hyena in June 1946 as an invisible character in the Li'l Abner newspaper strip. She was described as "the world's ugliest woman". Characters always reacted in fright when they saw her or an image of her but readers couldn't see her because she was hidden behind objects or out of frame. Eventually Capp organized a contest in which readers could send in their own graphic interpretations of what she might look like. The winner was cartoonist Basil Wolverton, whose design was first shown in the 21 October 1946 strip.
 * In Merho's comics series De Kiekeboes Mevrouw Stokvis, a friend of Moemoe Kiekeboe, is always mentioned or referred to, but has never actually been seen in the series.

Theatre
Unseen characters occur elsewhere in drama, including the plays of Eugene O'Neill, Tennessee Williams, and Edward Albee. Author Marie A. Wellington notes that in the 18th-century, Voltaire included unseen characters in a few of his plays, including Le Duc d’Alençon and L’Orphelin de la Chine.
