What film is recognized as the first film in the world with an entirely black cast?

Context: William D. Foster, sometimes referred to as Bill Foster, was a pioneering African-American film producer who was an influential figure in the Black film industry in the early 20th century, along with others such as Oscar Micheaux. He was the first African American to found a film production company, establishing the Foster Photoplay Company in Chicago in 1910. Foster had a vision for the African-American community to portray themselves as they wanted to be seen, not as someone else depicted them. He was influenced by the black theater community and wanted to break the racial stereotyping of blacks in film. He was an actor and writer under the stage name Juli Jones, as well as an agent for numerous vaudeville stars. His film The Railroad Porter, released in 1912, is credited as being the world's first film with an entirely black cast and director. The film is also credited with being the first black newsreel, featuring images of a YMCA parade. Foster's company produced four films that were silent shorts.

Answer: The Railroad Porter, produced by Bill Foster in 1912, is recognized as the first film in the world with a fully black cast and director.
