The Aviator is a 2004 American biographical drama film, directed by Martin Scorsese, and based largely on the book Howard Hughes: The Secret Life by Charles Higham. It tells the story of the eccentric aviation pioneer Howard Hughes, played by Leonardo DiCaprio, following his life from the late 1920s through the 1940s, a time when Hughes was directing and producing Hollywood movies as well as test-piloting his own groundbreaking new aircraft. The film also illustrates Hughes' descent into severe obsessive-compulsive disorder and reclusiveness.
The Aviator has no opening credits other than the title. The film begins with nine-year-old Hughes, supposedly in 1914, being bathed by his mother, who warns him of disease: "You are not safe."
The film next shows him in 1927, as a 22-year old preparing to direct Hell's Angels. Hiring Noah Dietrich (John C. Reilly) to run Hughes Tool Co, while he oversees the flight sequences for the film, Hughes becomes obsessesed with shooting the film realistically, even re-shooting the dogfight himself. By 1929, with the film finally complete, when The Jazz Singer is released, Hughes re-shoots the film for sound, costing another year and $1.7 million. Nevertheless, Hell's Angels is a huge hit, and Hughes makes Scarface and The Outlaw. However, there is one goal he relentlessly pursues: aviation. During this time, he also pursues Katharine Hepburn (Cate Blanchett). The two go to nightclubs, play golf and fly together, and as they grow closer, move in together as well. During this time Hepburn becomes a major support and confidant to Hughes, and helps alleviate the symptoms of his obsessive-compulsive disorder. As Hughes' fame grows, he is seen with more starlets.
