1914 film
Judith of Bethulia (1914) is an American film starring Blanche Sweet and Henry B. Walthall, and produced and directed by D. W. Griffith, based on the play "Judith and the Holofernes" (1896) by Thomas Bailey Aldrich, which itself was an adaptation of the Book of Judith. The film was the first feature-length film made by pioneering film company Biograph, although the second that Biograph released. It is considered the earliest American made epic film.
Shortly after its completion and a disagreement Griffith had with Biograph executives on making more future feature-length films, Griffith left Biograph, and took the entire stock company with him. Biograph delayed the picture's release until 1914, after Griffith's departure, so that it would not have to pay him in a profit-sharing agreement they had.
