Context paragraphs:
Charles Villiers (actor): Charles Villiers was an Australian actor and occasional director who appeared in many silent films.

He was particularly well known for playing villains.

Hoot Gibson filmography: Gibson's career began in 1910 with early silent film "shorts", and he continued as a movie star once "talkies" were introduced, his first sound film being "The Long, Long Trail" (1929).  Primarily starring in Western films, Gibson worked with many directors, including John Ford, who would direct many popular American Westerns and Civil War films, over his fifty years of film production, including "The Horse Soldiers" (1959), starring John Wayne, in which Gibson played a supporting role.  As with many silent and early recordings, a number of Gibson's films are considered to be lost.

Kevin Brownlow: Kevin Brownlow (born 2 June 1938) is a British film historian, television documentary-maker, filmmaker, author, and film editor.  Brownlow is best known for his work documenting the history of the silent era.  Brownlow became interested in silent film at the age of eleven.  This interest grew into a career spent documenting and restoring film.  He has rescued many silent films and their history.  His initiative in interviewing many largely forgotten, elderly film pioneers in the 1960s and 1970s preserved a legacy of early mass-entertainment cinema.  Brownlow received an Academy Honorary Award at the 2nd Annual Governors Awards given by the Academy of Motion Picture Arts and Sciences on 13 November 2010.  This was the first occasion on which an Academy Honorary Award was given to a film preservationist.
