When Persuasion premieres on Netflix on 15 July, it will join the long, long list of Jane Austen adaptations – many, if not all, of which, take liberties. From a bedraggled (and butterfly-inducing) Colin Firth climbing out of a lake in the BBC’s Pride and Prejudice (1995) to teenage rom-com Clueless (1995) – based on the author’s 1815 novel Emma – the value of reinterpreting Austen’s fictional worlds is a truth universally acknowledged. But why – as in the (2016) film Pride and Prejudice and Zombies – do these particular stories and their characters remain … undead?
