Herbert Wilcox wrapped up his long and prestigious film career as the director of Heart of a Man, which was produced by Wilcox' actress wife Anna Neagle. British teen idol Frankie Vaughn plays a sailor with a penchant for bursting into song. Vaughn has no intention of making a living as a vocalist, but a chance meeting with a whimsical hobo, coupled with a deepening relationship with nightclub thrush Anne Heywood, convinces Vaughn to go for the gold in the music world. In addition to enhancing the already successful career of Frankie Vaughn, Heart of a Man also gave a big boost to Anthony Newley, who popped up in a comic supporting role. As for producer Anna Neagle, this was the second and last of her Frankie Vaughn vehicles; after appearing in one more film (The Lady is a Square [59]) she followed her husband's lead and gracefully exited the British film industry.
