Over the years I have necessarily viewed The Prestige several times on the big screen. Every time, I have overheard members of the audience talking about the film as they leave the theatre. They feel challenged, enjoyably mystified; they wonder aloud at what they have seen. They have obviously been made to think. Nolan should take heed. Inadvertently, Shone’s book has a non-Prestige effect. Like one of Nolan’s later films, you leave the book with your head spinning, marvelling at the sights you have glimpsed, but you are empty of thoughts or ideas or, in the end, much interest.
