Books are books, and movies are movies. I usually don’t want or expect any adaptation to copy its source — in fact, it’s usually in everyone’s best interests for a derivative work to strive to be its own thing, and not… well, derivative. But Tom Tykwer and Lana & Larry Wachowski’s Cloud Atlas turned out to be an astonishingly faithful adaptation of David Mitchell’s novel. For a book so sprawling and commonly deemed unadaptable, I fully expected more characters and incident to have been necessarily jettisoned. But almost everything is there, with most of the screenwriters’ additions coming in the form of structural changes rather than material.
Being so faithful to this particular book comes with a potential downside. One of the greatest pleasures to be had in the novel is its wide range of genres and tones. Sequences include a pulpy 70s thriller, a light-hearted old folks farce, a sci-fi dystopia, and a postapocalyptic wasteland. Each is familiar to a degree, but only insofar as Mitchell employs known genre tropes to his own ends. Each is written in a different voice, ranging from archaic historical vernacular to imaginary fractured and devolved languages of the far future.
