This film is often mistakenly considered a sequel to Four Daughters (1938) since it has the same primary cast (Claude Rains, John Garfield, Jeffrey Lynn, May Robson, Frank McHugh, Dick Foran, Gale Page, and the real life Lane sisters - Priscilla Lane, Rosemary Lane and Lola Lane - all in somewhat similar roles, most specifically Page and the Lanes portraying four sisters to Raines' father) and even the same director, Michael Curtiz, but technically is not - the actors play different characters in this film than in the earlier film. Four Wives (1939) and Four Mothers (1941) are true sequels to Four Daughters.
