Body swap

A body swap is a storytelling device seen in a variety of 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.
