An actor, actress, or player (see terminology) is a person who acts in a dramatic production and who works in film, television, theatre, or radio in that capacity. The ancient Greek word for an actor, hypokrites, when rendered as a verb means "to interpret"; in this sense, an actor is one who interprets a dramatic character.
