Documentary films constitute a broad category of nonfictional motion pictures intended to document some aspect of reality, primarily for the purposes of instruction or maintaining a historical record. A 'documentary film' was originally shot on film stock — the only medium available — but now includes video and digital productions that can be either direct-to-video, made as a television program or released for screening in cinemas. "Documentary" has been described as a "filmmaking practice, a cinematic tradition, and mode of audience reception" that is continually evolving and is without clear boundaries.

In popular myth, the word 'documentary' was coined by Scottish documentarian John Grierson in his review of Robert Flaherty's film Moana (1926), published in the New York Sun on 8 February 1926, written by "The Moviegoer" (a pen name for Grierson).

Grierson's principles of documentary were that cinema's potential for observing life could be exploited in a new art form; that the "original" actor and "original" scene are better guides than their fiction counterparts to interpreting the modern world; and that materials "thus taken from the raw" can be more real than the acted article. In this regard, Grierson's definition of documentary as "creative treatment of actuality" has gained some acceptance, with this position at variance with Soviet film-maker Dziga Vertov's provocation to present "life as it is" (that is, life filmed surreptitiously) and "life caught unawares" (life provoked or surprised by the camera).

Bob Hope, KBE, KCSG, KSS (born Leslie Townes Hope; May 29, 1903 – July 27, 2003) was an English-born American comedian and actor who appeared in vaudeville, on Broadway, and in radio, television and movies. He was also noted for his work with the US Armed Forces and his numerous USO shows entertaining American military personnel. Throughout his long career, he was honored for his humanitarian work. In 1996, the U.S. Congress honored Bob Hope by declaring him the "first and only honorary veteran of the U.S. armed forces." Bob Hope appeared in or hosted 199 known USO shows.

Hope was born in Eltham, London, England, the fifth of seven sons. His English father, William Henry Hope, was a stonemason from Weston-super-Mare, Somerset, and his Welsh mother, Avis Townes, was a light opera singer from Barry who later worked as a cleaning woman. She married William Hope in April 1891 and the couple set up home at 12 Greenwood Street in the town, then moved to Whitehall and St George in Bristol, before eventually moving to Cleveland, Ohio in 1908. The family emigrated to the United States aboard the SS Philadelphia, and passed inspection at Ellis Island on March 30, 1908. Hope became a U.S. citizen in 1920 at the age of 17. In a 1942 legal document, Hope's legal name is given as Lester Townes Hope. His name on the Social Security Index is also listed as Lester T. Hope. His name as registered at birth was Leslie Towns [sic] Hope.

William H. Bonney (born William Henry McCarty, Jr.) est. November 23, 1859 – c. July 14, 1881, better known as Billy the Kid but also known as Henry Antrim, was a 19th-century American gunman who participated in the Lincoln County War and became a frontier outlaw in the West. According to legend, he killed 21 men, but he is generally accepted to have killed between four and nine.

McCarty (or Bonney, the name he used at the height of his notoriety) was 5 feet 8 inches (173 cm) to 5 feet 9 inches (175 cm) tall with blue eyes, a smooth complexion, and prominent front teeth. He was said to be friendly and personable at times, and many recalled that he was as "lithe as a cat". Contemporaries described him as a "neat" dresser who favored an "unadorned Mexican sombrero". These qualities, along with his cunning and celebrated skill with firearms, contributed to his paradoxical image, as both a notorious outlaw and beloved folk hero.

Relatively unknown during most of his lifetime, Billy was catapulted into legend in 1881 when New Mexico's governor, Lew Wallace, placed a price on his head. In addition, the Las Vegas Gazette (Las Vegas, New Mexico) and the New York Sun carried stories about his exploits. Many other newspapers followed suit. After his death, several biographies were written that portrayed the Kid in varying lights.
