Dirigible is Frank Capra's 1931 adventure film about the competition between American naval fixed-wing and airship pilots to reach the South Pole by air.

Fay Wray stars, as do Jack Holt and Ralph Graves, who also played fliers in Capra's 1929 talkie, Flight. In fact this film had been intended to emulate the success of 1927's Wings, another movie with a very similar plot. The film was characterized as "marginally science fictional" by scifilm.org. (Capra later planned to make a fully science fictional movie but was never able to.)

When famed explorer Louis Rondelle (Hobart Bosworth) requests the U.S. Navy's assistance in reaching the South Pole, officer Jack Bradon (Jack Holt) convinces Rear Admiral John S. Martin (Emmett Corrigan) to offer his dirigible, the USS Pensacola, for the attempt.

Jack requests his best friend "Frisky" Pierce (Ralph Graves) to pilot the biplane that will be carried on the airship. Frisky, who is adventurous to the point of recklnessness, is eager to go even though he has just completed a record-setting coast-to-coast flight and has barely spent any time with his wife Helen (Fay Wray). Basking in the acclaim, he has even forgotten to read the sealed love letter she gave him to open when he arrived.

An airship or dirigible is a type of aerostat or "lighter-than-air aircraft" that can be steered and propelled through the air using rudders and propellers or other thrust mechanisms. Unlike aerodynamic aircraft such as fixed-wing aircraft and helicopters, which produce lift by moving a wing through the air, aerostatic aircraft stay aloft by having a large "envelope" filled with a gas which is less dense than the surrounding atmosphere. The first lifting gas used was hydrogen, although this had well-known concerns over its flammability. Helium was rare in most parts of the world, but large amounts were discovered in the USA. This meant that this non-flammable gas was rarely used for airships outside of the USA. All modern airships, since the 1960s, use helium.

The main types of airship are non-rigid (or blimps), semi-rigid and rigid. Blimps are "pressure" airships where internal pressure, maintained by forcing air into an internal ballonet, is used to both maintain the shape of the airship and its structural integrity. Semi-rigid airships maintain the envelope shape by internal pressure, but have some form of internal support such as a fixed keel to which control and engine gondolas and stabilizers and steering surfaces are mounted. Rigid airships have a structural framework which maintain the shape and carries all loads such as from gondolas, engines. The framework contains numerous balloons, known as "gas cells" or "gasbags" which supply the static lift without having to bear any structural loading. Rigid airships are often called Zeppelins, as the type was invented by Count Zeppelin and the vast majority of rigid airships built were manufactured by the firm he founded.

A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry.

Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating – or indoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer.

Films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.

Georges Méliès (English pronunciation: /mɛ.li.'ez/); (8 December 1861 – 21 January 1938), full name Marie-Georges-Jean Méliès, was a French illusionist and filmmaker famous for leading many technical and narrative developments in the earliest days of cinema. Méliès, a prolific innovator in the use of special effects, accidentally discovered the substitution stop trick in 1896, and was one of the first filmmakers to use multiple exposures, time-lapse photography, dissolves, and hand-painted color in his work. Because of his ability to seemingly manipulate and transform reality through cinematography, Méliès is sometimes referred to as the first "Cinemagician". Two of his most well-known films are A Trip to the Moon (1902) and The Impossible Voyage (1904). Both stories involve strange, surreal voyages, somewhat in the style of Jules Verne, and are considered among the most important early science fiction films, though their approach is closer to fantasy. Méliès was also an early pioneer of horror cinema, which can be traced back to his Le Manoir du diable (1896).

The Shadow is a collection of serialized dramas, originally in pulp magazines, then on 1930s radio and then in a wide variety of media, that follow the exploits of the title character, a crimefighting vigilante in the pulps, which carried over to the airwaves as a "wealthy, young man about town" with psychic powers. One of the most famous pulp heroes of the 20th century, The Shadow has been featured in comic books, comic strips, television, video games, and at least five motion pictures. The radio drama is well-remembered for those episodes voiced by Orson Welles.

Introduced as a mysterious radio narrator by David Chrisman, William Sweets and Harry Engman Charlot for Street and Smith Publications, The Shadow was fully developed and transformed into a pop culture icon by pulp writer Walter B. Gibson.

The Shadow debuted on July 31, 1930, as the mysterious narrator of the Street and Smith radio program Detective Story Hour. After gaining popularity among the show's listeners, the narrator became the star of The Shadow Magazine on April 1, 1931, a pulp series created and primarily written by the prolific Gibson.
