'In A Theory of Adaptation, Linda Hutcheon takes as a premise that adaptation is ubiquitous as a process, as a creative practice and as a product. Hutcheon's study investigates how adaptation works across all media and all genres including theatre, cover songs, video and computer games, and even theme parks. However, much of the theoretical discourse on adaptation is constrained still by narrow understandings of the transfer of a single source text from one medium to a text in a different medium, usually concentrating on novels adapted to film and television.'
