I hardly comment trailers here, but in this case I felt like I should, since the movie seems to deserve as much exposition as it can (not that I'm so powerful in this internet thing, you see?). Of course maybe I'm just saying this because I'm a great fan of the book. Who knows?
Whatever the truth is, watch the trailer and see what you think. The movie is directed by Walter Salles and has Mr. Francis Ford Copolla as executive producer.
