The Aviator is a 2004 American biographical drama film directed by Martin Scorsese, written by John Logan, produced by Graham King and Michael Mann and featuring an ensemble cast starring Leonardo DiCaprio, Cate Blanchett, Kate Beckinsale, Alan Alda, John C. Reilly and Alec Baldwin.

Martin Scorsese directed this fast-moving, epic-scale biopic documenting the life and loves one of the most colorful Americans of the 20th century, Howard Hughes. The Aviator follows Hughes (played by Leonardo DiCaprio) as the twentysomething millionaire, having already made a fortune improving the design of oil-drilling bits, comes to Hollywood with an interest in getting into the picture business. It doesn't take long for Hughes, with his passion for airplanes, to jump from producer to director of his first major film project, a World War I air epic called Hell's Angels, which took three years to complete thanks to the shift from silent to sound filming and Hughes' relentless perfectionism. However, the film was a massive hit, and the eccentric inventor became a mogul in Hollywood, making Jean Harlow (Gwen Stefani) a star and enjoying a romance with Katharine Hepburn (Cate Blanchett). But Hollywood's old-boy network never fully accepted Hughes, and in time his passion for flying began to reclaim his attentions as he began designing new planes, setting air speed records, flying around the world, and risking his life testing aircraft. Hughes also found time to romance Ava Gardner (Kate Beckinsale) and founded his own airline, Trans-World Airlines, though as his ideas became bolder, his approach became more eccentric, and he gained many powerful enemies, including the head of Pan-American Airlines, Juan Trippe (Alec Baldwin), and Senator Ralph Owen Brewster (Alan Alda), who attempted to prove that Hughes' radical design ideas were actually part of an effort to bilk taxpayers for millions of dollars through government contracts.

The film received highly positive reviews with the review tallying website Rotten Tomatoes reporting that 194 out of the 203 reviews they tallied were positive for a score of 87% and certification of "Fresh".Roger Ebert of Chicago Sun-Times gave the film four stars out of four and described the film and its subject, Howard Hughes, in these terms: "What a sad man. What brief glory. What an enthralling film, 166 minutes, and it races past. There's a match here between Scorsese and his subject, perhaps because the director's own life journey allows him to see Howard Hughes with insight, sympathy– and, up to a point, with admiration. This is one of the year's best films."

The Aviator grossed $102,610,330 in the United States and Canada and$111,131,129 overseas. In total, the film has grossed $213,741,459 worldwide.
