One of the better "Abie's Irish Rose" derivations of the late 1920s, The Shamrock and the Rose was adapted from a play by Owen Davis Sr. Set in New York's Lower East Side, "where the melting pot boils over," it's the story of a Jewish girl (Olive Hasbrouck) who falls in love with an Irish boy (Edmund Burns). While the hero's parents are delighted at the prospect of his marriage, the girl's mother and father are beside themselves, prompting the heroine to consider converting to Catholicism. She is diverted from this course by an understanding priest (former matinee idol Maurice Costello, in a very minor role) who exhorts her to take pride in her Hebraic heritage. The differences between the two families are settled comedically a year or so later, when the heroine is rushed to the maternity hospital. The film's best performance is delivered by Keystone veteran Mack Swain as the hero's boisterous father.
