One of several Anna Neagle-Tulio Carminatti vehicles of the 1930's, London Melody was one of five films directed in 1937 by Neagle's future husband Herbert Wilcox. This time around, Carminatti is cast as Marius Andreani, a cultured Italian diplomat. While in London on business, Marius makes the chance acquaintance of boisterous cockney street entertainer Jacqueline (Neagle). It's love at first sight, but hero and heroine must undergo a dizzying series of roadblocks and misunderstandings before the climactic clinch. Meanwhile, Jacqueline rises to the top of show-business success, never dreaming (until the end, at least) that it's all the secret handiwork of faithful Marius.
