Set in the Royal Navy during the Napoleonic Wars, O'Brian's twenty-volume series centers on the enduring friendship between naval officer Jack Aubrey and physician (and spy) Stephen Maturin. The Far Side of the World, the tenth book in the series, was adapted into a 2003 film directed by Peter Weir and starring Russell Crowe and Paul Bettany. The film was nominated for ten Oscars, including Best Picture.
