Alfred E. Green directs the political satire The Dark Horse, starring Bette Davis early in her career. The progressive party nominates moronic candidate Zachary Hicks (Guy Kibbee) for governor. Party secretary Kay Russell (Davis) wants to hire her sweetheart, Hal Blake (Warren William), for campaign manager, even though he is in jail for not paying his alimony. Impressed with his slick behavior, the campaign committee bails him out of jail and he goes to work. He teaches Hicks to give cryptic answers to journalists and makes him memorize a speech by Abraham Lincoln. During the big debate, conservative opponent William A. Underwood (Berton Churchill) quotes Lincoln and Hicks calls him a plagiarist. Eventually, Blake's ex-wife, Maybelle (Vivienne Osborne) shows up demanding her alimony payments. The climactic scene involves a set-up at a rural mountain cabin and confusing marital arrangements. Also starring Frank McHugh as aide Joe and Sam Hardy as the conservative manager Mr. Black. Hollywood mogul Darryl F. Zanuck received co-writing credits for the screenplay under the pseudonymn Melville Crossman.
