With this spectacular romantic adventure, a new era of Hollywood swashbuckling was born, as was a devilishly dashing star named Errol Flynn. He brings boundless charisma to the role of an idealistic Irish physician who, declared a traitor to England and sold into slavery in the New World, takes his revenge by transforming himself into the notorious pirate Captain Blood. The groundbreaking symphonic score by Erich Wolfgang Korngold, marking the emergence of the Warner Bros. music department as a vital element in the studio’s moviemaking; the spitfire chemistry between Flynn and Olivia de Havilland in the first of their iconic pairings; the rousing naval-battle finale—all come together under the expert direction of Michael Curtiz to form an exemplar of classic film craftsmanship sailing full speed ahead.
