Don Ameche, renowned for his portrayal of the telephone's inventor in The Story of Alexander Graham Bell, here plays another prolific inventor: Hiram Stevens Maxim, whose many creations include a machine gun, a mousetrap, the curling iron and various manufacturing mechanisms. The film is a love story, with Myrna Loy portraying Maxim's bride, who sought wealth but found love. It is a growing-up story, with Bobby Driscoll playing Maxim's son. And it is a affectionate evocation of time and place based on the son's popular remembrance A Genius in the Family and filmed during the era of the comparably nostalgic Life with Father, I Remember Mama and Stars in My Crown. Memory warmly endures in So Goes My Love.
