What is a retelling of a story in a different form or genre called?

A retelling of a story in a different form or genre is often referred to as an "adaptation." This process involves transforming the original narrative into a new medium, such as turning a novel into a film, a play, or even a graphic novel. Adaptations can also involve reinterpreting the story within a different cultural or historical context. Such creative reinterpretations allow for new insights and perspectives on the original material.
