David Mitchell, author of Cloud Atlas, is apparently happy with how the movie turned out. He should be. The movie -- faithful in spirit but unfaithful in many details -- does something I would have sworn was impossible: it soars like the book.
What is Cloud Atlas about? In various ways, it examines the nature of tyranny and the human instinct toward freedom. It is about the search for truth and the many obstacles that stand in the way of that search.
