Book excerpt: Just as a work of self-reflexive 'metafiction' - and the experience of reading it - differ from other types of literature, the work and the experience of viewing films that adapt metafiction are distinct from those of other films, and from other film adaptations of literary works. This book explores the adaptation of children's metafictions, including works such as Inkheart, The Invention of Hugo Cabret and the Harry Potter series. Not only are the plot devices of books and reading explored on screen in these adaptations, but so is the nature of transmedial adaptation itself - the act of representing one work of art in another medium. Analysing the 'work' done by children's metafiction and the experience of reading it, Casie E. Hermansson situates the adaptations of these types of books to film within contemporary adaptation criticism.
