Practice - Invisible Theater

Invisible theatre is a form of theatrical performance that is enacted in a place where people would not normally expect to see one, for example in the street or in a shopping centre. The Brazilian Theatre practirioner Augusto Boal developed the form during his time in Argentina in the 1970s as part of his Theatre of the Oppressed, which focused on oppression and social issues. Boal went on to develop forum theatre. Invisible theatre can give people who would not normally have the chance to see plays the opportunity to do so—or, as is often the case, it can be performed without the knowledge of its audience, which in such a scenario would consist of whoever happens to wander by. This can be done in order to help actors make a point publicly in much the same motivational vein as graffiti or political demonstration, or it can be done in order to help actors gain a sense of what a realistic reaction might be to a certain scenario; for example, a heated argument over a political or social issue. This type of theatre is performed in public on unexpected bystanders, whom the actors will try to get unknowingly involved in the scene.
