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.
Body swap A body swap is a storytelling device seen in a variety of science and supernatural fiction, in which two people (or beings) exchange minds and end up in each other's bodies. In media such as television and film, the device is an opportunity for two actors to temporarily play each other's characters, although in some cases, dialogue is dubbed by the original actors.
