Last week I linked to a New York Times article on the difficulty of knowing which books become best sellers and which books become dust-covered duds, and compared the book industry’s challenge to that of the movie industry’s. Kim has a great post today on last week’s verdict in the case that pitted movie production company Crusader against Clive Cussler, author of best-selling book “Sahara.” Sahara the movie turned out to be a disastrous failure at the box office, where it made only $68 million domestically. While $68 million is a big pile of money, the movie reportedly cost about a quarter-billion dollars to produce and promote.
