What barrier does Hannah Baxter remove when she acknowledges and comments directly to the audience?
Fourth wall The fourth wall is a performance convention in which an invisible, imagined wall separates actors from the audience. While the audience can see through this "wall", the convention assumes, the actors act as if they cannot. From the 16th century onwards, the rise of illusionism in staging practices, which culminated in the realism and naturalism of the theatre of the 19th century, led to the development of the fourth wall concept.
Rights of audience In common law, a right of audience is generally a right of a lawyer to appear and conduct proceedings in court on behalf of their client. In English law, there is a fundamental distinction between barristers, who have rights of audience in the superior courts, and solicitors, who have rights of audience in the lower courts, unless a certificate of advocacy is obtained, which allows a solicitor to represent clients in the superior courts also. However, there is no such distinction in American law.
