Doctor Rhythm (1938)

Stars:

Bing Crosby, Mary Carlisle, Beatrice Lillie

Bing Crosby plays the melodic medico of the title. To help cover for his ailing policeman pal (Andy Devine), Crosby takes the policeman's latest assignment and becomes the bodyguard for a loopy but wealthy matron (Bea Lillie). Bing falls in love with the lady's niece (Mary Carlisle), expressing his ardor in song. When the older woman becomes the target of thieves, it's Bing to the rescue. Based on the O. Henry yarn "The Badge of Policeman O'Roon", Dr. Rhythm is a satisfactory Bing Crosby vehicle, with the legendary Bea Lillie permitted a few choice moments in a rare screen appearance.
