Break of Hearts is a 1935 RKO film starring Katharine Hepburn and Charles Boyer. The screenplay was written by the team of Sarah Y. Mason and Victor Heerman, with Anthony Veiller, from a story by Lester Cohen, specifically for Hepburn. Originally Break of Hearts was intended as a vehicle for Hepburn and John Barrymore. The film was promoted by RKO's advertising department with the catch phrase: "The star of a million moods together with the new idol of the screen." (Francis Lederer actually was first signed-up lead, but the producers replaced him with Charles Boyer.)
