The 1940s was the decade that started on January 1, 1940, and ended on December 31, 1949. This was the fifth decade of the 20th century.

The Second World War took place in the first half of the decade, which had a profound effect on most countries and people in Europe, Asia and elsewhere. The consequences of the war lingered well into the second half of the decade, with a war-weary Europe divided between the jostling spheres of influence of the West and the Soviet Union. To some degree internal and external tensions in the post-war era were managed by new institutions, including the United Nations, the welfare state and the Bretton Woods system, providing to the post–World War II boom, which lasted well into the 1970s. However the conditions of the post-war world encouraged decolonialization and emergence of new states and governments, with India, Pakistan, Israel, Vietnam and others declaring independence, rarely without bloodshed. The decade also witnessed the early beginnings of new technologies (including computers, nuclear power and jet propulsion), often first developed in tandem with the war effort, and later adapted and improved upon in the post-war era.

The Walt Disney Studios released the animated feature films Pinocchio (1940), Dumbo (1941), Fantasia (1941), and Bambi (1942).

Although the 1940s was a decade dominated by World War II, important and noteworthy films about a wide variety of subjects were made during that era. Hollywood was instrumental in producing dozens of classic films during the 1940s, several of which were about the war and some are on most lists of all-time great films. European cinema survived although obviously curtailed during wartime and yet many films of high quality were made in the United Kingdom, France, Italy, the Soviet Union and elsewhere in Europe. The cinema of Japan also survived. Akira Kurosawa and other directors managed to produce significant films during the 1940s.

Film Noir, a film style that incorporated crime dramas with dark images, became largely prevalent during the decade. Films such as The Maltese Falcon and The Big Sleep are considered classics and helped launch the careers of legendary actors such as Humphrey Bogart and Ava Gardner. The genre has been widely copied since its initial inception.

In France during the war the tour de force Children of Paradise directed by Marcel Carné (1945), was shot in Nazi occupied Paris.^[5][6][7] Memorable films from post-war England include David Lean's Great Expectations (1946) and Oliver Twist (1948), Carol Reed's Odd Man Out (1947) and The Third Man (1949), and Powell and Pressburger's A Matter of Life and Death (1946), Black Narcissus (1946) and The Red Shoes (1948), Laurence Olivier's Hamlet, the first non-American film to win the Academy Award for Best Picture and Kind Hearts and Coronets (1949) directed by Robert Hamer. Italian neorealism of the 1940s produced poignant movies made in post-war Italy. Roma, città aperta directed by Roberto Rossellini (1945), Sciuscià directed by Vittorio De Sica (1946), Paisà directed by Roberto Rossellini (1946), La terra trema directed by Luchino Visconti (1948), The Bicycle Thief directed by Vittorio De Sica (1948), and Bitter Rice directed by Giuseppe De Santis (1949), are some well-known examples.

In Japanese cinema The 47 Ronin is a 1941 black and white two-part Japanese film directed by Kenji Mizoguchi. The Men Who Tread on the Tiger's Tail (1945), and the post-war Drunken Angel (1948), and Stray Dog (1949), directed by Akira Kurosawa are considered important early works leading to his first masterpieces of the 1950s. Drunken Angel (1948), marked the beginning of the successful collaboration between Kurosawa and actor Toshirō Mifune that lasted until 1965.

Music[link]

This section requires expansion.

• The most popular music style during the 1940s was swing, which prevailed during World War II. In the later periods of the 1940s, less swing was prominent and crooners like Frank Sinatra, along with genres such as bebop and the earliest traces of rock and roll, were the prevalent genre.

Fashion[link]

Even with the challenges imposed by shortages in rayon, nylon, wool, leather, rubber, metal (for snaps, buckles, and embellishments) and even the amount of fabric that could be used in any one garment, the fashion industry's wheels kept chugging slowly along, producing what it could. After the fall of France in 1940, Hollywood drove fashion in the United States almost entirely, with the exception of a few trends coming from war torn London in 1944 and 1945, as America's own rationing hit full force, and the idea of function seemed to overtake fashion, if only for a few short months until the end of the war. Fabrics shifted dramatically as rationing and wartime shortages controlled import items such as silk and furs. Floral prints seem to dominate the early 1940s, with the mid-to-late 1940s also seeing what is sometimes referred to as "atomic prints" or geometric patterns and shapes. The color of fashion seemed to even go to war, with patriotic nautical themes and dark greens and khakis dominating the color palates, as trousers and wedges slowly replaced the dresses and more traditional heels due to shortages in stockings and gasoline.

Sports[link]

During the 1940s Sporting events were disrupted and changed by the events that engaged and shaped the entire world. The 1940 and 1944 Olympic Games were cancelled because of World War II. During World War II in the United States Heavyweight Boxing Champion Joe Louis and numerous stars and performers from American baseball and other sports served in the armed forces until the end of the war. Among the many baseball players (including well known stars) who served during World War II were Moe Berg, Joe DiMaggio, Bob Feller, Hank Greenberg, Stan Musial (in 1945), Warren Spahn, and Ted Williams. They like many others sacrificed their personal and valuable career time for the benefit and well being of the rest of society. The Summer Olympics were resumed in 1948 in London and the Winter games were held that year in St. Moritz, Switzerland.

Hall of Famer Hank Greenberg

During the early 1940s World War II had an enormous impact on Major League Baseball as many players including many of the most successful stars joined the war effort. After the war many players returned to their teams, while the major event of the second half of the 1940s was the 1945 signing of Jackie Robinson to a players contract by Branch Rickey the general manager of the Brooklyn Dodgers. Signing Robinson opened the door to the integration of Major League Baseball finally putting an end to the professional discrimination that had characterized the sport since the 19th century.

Boxing[link]

During the mid-1930s and throughout the years leading up to the 1940s Joe Louis was an enormously popular Heavyweight boxer. In 1936 he lost an important 12 round fight (his first loss) to the German boxer Max Schmelling and he vowed to meet Schmelling once again in the ring. Louis's comeback bout against Schmelling became an international symbol of the struggle between the USA and democracy against Nazism and Fascism. When on June 22, 1938, Louis knocked Schmelling out in the first few seconds of the first round during their rematch at Yankee Stadium, his sensational comeback victory riveted the entire nation. Louis enlisted in the U.S. Army on January 10, 1942 in response to the Japanese attack on Pearl Harbor. Louis's cultural impact was felt well outside the ring. He is widely regarded as the first African American to achieve the status of a nationwide hero within the United States, and was also a focal point of anti-Nazi sentiment leading up to and during World War II.^[9]

Career[link]

2004–2011[link]

Stone at the Zombieland world premiere, 2009

Stone launched a career in television after winning the role of Laurie Partridge on In Search of the New Partridge Family (2004), a VH1 talent competition reality show.^[10] The resulting show, The New Partridge Family (2005), only produced a pilot episode. Stone next had appearances in the television series Medium, Malcolm in the Middle and Lucky Louie. In 2007, she had a regular role on the Fox drama Drive, playing Violet Trimble, until the series was cancelled. She also auditioned for Heroes, and overheard in the casting room "On a scale of 1 to 10, you are an 11" — the casting directors were referring to Hayden Panettiere, who was cast as Claire Bennet instead. Stone called this experience "rock bottom."^[11]

Stone made her feature film debut in the 2007 teen comedy Superbad, playing Jules, the love interest of lead character Seth (Jonah Hill). In 2008, she appeared in the comedy The Rocker, with Rainn Wilson. Stone played Amelia, the bass guitarist in a band featuring singer Teddy Geiger. Stone learned to play bass for the role.

Stone read the script before the project was optioned for production, and kept an eye on it along with her manager until preparations were made.^[24] She was attracted to the script because it was "funny and sweet" and her character was "fantastic from the first read" who was "fleshed [..] out so much in the script".^[24] When she found out that the film had gone into production, she met with Gluck to express her enthusiasm about the project.^[24] A few months later, the audition process started and Stone met again with Gluck to be one of the first actresses to audition.^[24] Stone was nominated for the 2011 Golden Globe Award for Best Actress in a Musical or Comedy for her role.^[25]
