Despite its Victrola-inspired title, His Master's Voice was a silent film (though it was released with an accompanying musical score, written by Gus Edwards, Howard Johnson and Irving Bibo, for the benefit of moviehouse pit orchestras). Rin-Tin-Tin wannabe Thunder the Dog stars as an army mutt during World War I. With Thunder's help, human co-star George Hackathorne overcomes his cowardice on the battlefield. Hackathorne then returns home to settle accounts with the crooked rival who stole his gal (Marjorie Daw). The novelty: His Master's Voice is related in flashback by Thunder himself, who is seen at the beginning and end of the film "telling" his story to his pups. ~ Hal Erickson, Rovi
