Question: Frederick Douglass and the White Negro and Land of Silence and Darkness are both what kind of film?
Context: Life and Times of Frederick Douglass is Frederick Douglass' third autobiography, published in 1881, revised in 1892.  Because of the emancipation of American slaves during and following the American Civil War, Douglass gave more details about his life as a slave and his escape from slavery in this volume than he could in his two previous autobiographies (which would have put him and his family in danger).  It is the only one of Douglass' autobiographies to discuss his life during and after the Civil War, including his encounters with American presidents such as Lincoln and Garfield, his account of the ill-fated "Freedman's Bank", and his service as the United States Marshall of the District of Columbia. My Bondage and My Freedom is an autobiographical slave narrative written by Frederick Douglass and published in 1855.  It is the second of three autobiographies written by Douglass, and is mainly an expansion of his first ("Narrative of the Life of Frederick Douglass"), discussing in greater detail his transition from bondage to liberty.  Following this liberation, Douglass, a former slave, went on to become a prominent abolitionist, speaker, author, and publisher. The Brewster-Douglass Housing Projects (officially named the Frederick Douglass Homes, and alternately named Frederick Douglass Projects, Frederick Douglass Apartments, Brewster-Douglass Homes, and Brewster-Douglass Projects) were the largest residential housing project owned by the city of Detroit, located in the Brush Park section on the east side of Detroit, Michigan, near the Chrysler Freeway, Mack Avenue and St. Antoine Street.  The housing project is named after Frederick Douglass, African American abolitionist, author, and reformer. Frederick Douglass Circle is a traffic circle located at the northwest corner of Central Park at the intersection of Eighth Avenue (Frederick Douglass Boulevard and Central Park West) and 110th Street (Cathedral Parkway and Central Park North) in the New York City borough of Manhattan.  The traffic circle is named for the American abolitionist, women’s suffragist, editor, orator, author, statesman and reformer Frederick Douglass. Frederick Douglass and the White Negro is a documentary film originally released in 2008 (Irish language version entitled Frederick Douglass agus na Negroes Bána). The Frederick Douglass National Historic Site, administered by the National Park Service, is located at 1411 W St., SE in Anacostia, a neighborhood east of the Anacostia River in Southeast Washington, D.C..  Established in 1988 as a National Historic Site, the site preserves the home and estate of Frederick Douglass, one of the most prominent African Americans of the 19th century.  Douglass lived in this house, which he named Cedar Hill, from 1877 until his death in 1895.  Perched high on a hilltop, the site also offers a sweeping view of the U.S. Capitol and the Washington D.C. skyline. Edward Covey (December 2, 1805 – May 2, 1875), a farmer of Talbot County, Maryland, was an early 19th-century American slaveholder.  He is described by Frederick Douglass in "My Bondage and My Freedom" (published in 1855) as a "first rate hand at breaking young negroes".  In "The Narrative of the Life of Frederick Douglass", Douglass writes that "Mr. Covey had acquired a very high reputation for breaking young slaves, and this reputation was of immense value to him.  It enabled him to get his farm tilled with much less expense to himself than he could have had it done without such a reputation".  In 1833, Douglass was rented to Covey for a year so that Covey would break the teenage slave's spirit. Francis T. Nicholls High School and later Frederick Douglass High School are the former names of a high school at 3820 St. Claude Avenue in the Ninth Ward of New Orleans, Louisiana.  Initially named for Francis T. Nicholls, a former Confederate general, governor of Louisiana, and Chief Justice of the Louisiana Supreme Court, the school opened as a segregated white institution on January 29, 1940.  During the middle 1990s, having since long been desegregated, Nicholls High School was renamed in honor of the African-American abolitionist Frederick Douglass of Maryland.  The school has since been again reorganized and renamed.  The Douglass building is now home to a public charter school known as KIPP Renaissance High School which earned an "A" letter grade from the Louisiana Department of Education in 2016. Land of Silence and Darkness (German: Land des Schweigens und der Dunkelheit ) is a 1971 documentary film about deaf-blind people and their experience of life.  The film was written, directed, and produced by Werner Herzog.  Rolf Illig provided narration. Lewis Henry Douglass (1840–1908) was the oldest son of Frederick Douglass and his first wife Anna Murray Douglass.  He was born in New Bedford, Massachusetts.  Douglass was well educated and as a boy apprenticed, in Rochester, New York, as a typesetter for his father's newspapers "The North Star" and "Douglass' Weekly".  He joined the Union Army on March 25, 1863, only two months after the Emancipation Proclamation allowed African Americans to see combat in the Union Army.  He fought for one of the first official African American units in the United States during the Civil War, the famed 54th Massachusetts Infantry Regiment.  Shortly after joining the army, Douglass attained the rank of Sergeant Major, the highest rank a black man could reach.  He took part in the Battle of James Island, the Battle of Olustee, the Second Battle of Fort Wagner.  At the Second Battle of Fort Wagner, half of his regiment was killed, but this battle turned the public's attention toward the sacrifices made by African Americans in the war.  Douglass addressed the bravery of the African American troops in a letter to his future wife Helen Amelia Loguen:
