Millard Webb: Millard Webb (6 December 1893 – 21 April 1935), was an American screenwriter and director.  He directed 20 films between 1920 and 1933.  His best-known film is the 1926 silent John Barrymore adventure "The Sea Beast" costarring Dolores Costello.

The Sea Beast: The Sea Beast is a 1926 American silent drama film directed by Millard Webb, starring John Barrymore and Dolores Costello.  The film was a major commercial success and one of the biggest pictures of 1926.  "The Sea Beast" is an adaptation of the novel "Moby-Dick" by Herman Melville, a story about a monomaniacal hunt for a great white whale.  However, the film alters the novel's plotline by establishing prequel and sequel elements that are not in the original story—such as the romancing of Esther and Ahab's safe return, respectively—and substitutes a happy ending for Melville's original tragic one.  Some of the characters in the film do not appear in Melville's original novel.

It was one of the early films of John Wayne who was only aged 20 in the film.  He too played a college footballer.  A mute silent print was transferred onto 16mm film by Associated Artists Productions in the 1950s and in 1960s by United Artists Television.  Prints of the film are preserved at the Library of Congress and the Wisconsin Center for Film and Theater Research, Madison.
