The 1940s: the war and post-war years

The desire for wartime propaganda created a renaissance in the film industry in Britain, with realistic war dramas like 49th Parallel (1941), Went the Day Well? (1942), The Way Ahead (1944) and Noel Coward and David Lean's celebrated naval film In Which We Serve in 1942, which won a special Academy Award. These existed alongside more flamboyant films like Michael Powell and Emeric Pressburger's The Life and Death of Colonel Blimp (1943), A Canterbury Tale (1944) and A Matter of Life and Death(1946), as well as Laurence Olivier's 1944 film Henry V, based on the Shakespearean history Henry V. The success of Snow White and the Seven Dwarfs allowed Disney to make more animated features like Pinocchio (1940), Fantasia (1940), Dumbo (1941) and Bambi (1942).

The onset of US involvement in World War II also brought a proliferation of movies as both patriotism and propaganda. American propaganda movies included Desperate Journey, Mrs. Miniver, Forever and a Day and Objective Burma. Notable American films from the war years include the anti-Nazi Watch on the Rhine (1943), scripted byDashiell Hammett; Shadow of a Doubt (1943), Hitchcock's direction of a script by Thornton Wilder; the George M. Cohan biopic, Yankee Doodle Dandy (1942), starringJames Cagney, and the immensely popular Casablanca, with Humphrey Bogart. Bogart would star in 36 films between 1934 and 1942 including John Huston's The Maltese Falcon (1941), one of the first movies now considered a classic film noir. In 1941, RKO Pictures released Citizen Kane made by Orson Welles. It is often considered the greatest film of all time. It would set the stage for the modern motion picture, as it revolutionized film story telling.

The strictures of wartime also brought an interest in more fantastical subjects. These included Britain's Gainsborough melodramas (including The Man in Grey and The Wicked Lady), and films like Here Comes Mr. Jordan, Heaven Can Wait, I Married a Witch and Blithe Spirit. Val Lewton also produced a series of atmospheric and influential small-budget horror films, some of the more famous examples being Cat People, Isle of the Dead and The Body Snatcher. The decade probably also saw the so-called "women's pictures", such as Now, Voyager, Random Harvest and Mildred Pierce at the peak of their popularity.

1946 saw RKO Radio releasing It's a Wonderful Life directed by Frank Capra. Soldiers returning from the war would provide the inspiration for films like The Best Years of Our Lives, and many of those in the film industry had served in some capacity during the war. Samuel Fuller's experiences in World War II would influence his largely autobiographical films of later decades such as The Big Red One. The Actor's Studio was founded in October 1947 by Elia Kazan, Robert Lewis, and Cheryl Crawford, and the same year Oskar Fischinger filmed Motion Painting No. 1.

In 1943, Ossessione was screened in Italy, marking the beginning of Italian neorealism. Major films of this type during the 1940s included Bicycle Thieves, Rome, Open City, and La Terra Trema. In 1952 Umberto D was released, usually considered the last film of this type.

In the late 1940s, in Britain, Ealing Studios embarked on their series of celebrated comedies, including Whisky Galore!, Passport to Pimlico, Kind Hearts and Coronets andThe Man in the White Suit, and Carol Reed directed his influential thrillers Odd Man Out, The Fallen Idol and The Third Man. David Lean was also rapidly becoming a force in world cinema with Brief Encounter and his Dickens adaptations Great Expectations and Oliver Twist, and Michael Powell and Emeric Pressburger would experience the best of their creative partnership with films like Black Narcissus and The Red Shoes.
