Но сам автор признает, что фильм мало похож на оригинал
The Prestige is very loosely based on the Christopher Priest novel, of the same name; Nolan took those challenges of creating a book onto the big screen head on. "We put the most interesting aspects of what Priest put in there; it's a very large book, and there's a lot going on there. We had to throw away a lot of the ideas in the book in order to make it work as a film. But I like to think it captures the essence of the book. We've kept all the main elements; I think he liked the screenplay, so I think we got the blessing of him early on. There are a lot of things it does, story wise, that he does in the novel, in terms of steering the reader, with holding information. You can't do that in film; you have to find the cinematic equivalent of that."
