It was the actor's first starring role in a full-length feature and the film that launched his career. 　　The plot was a merging of two stories, Bronson Howard's play The Henrietta and the novel The New Henrietta by Victor Mapes and Winchell Smith, which was meant to be an adaption of Howard's play.
