Alfred Lord Tennyson's poem, "Enoch Arden," about a fisherman presumed lost at sea who returns to find his wife remarried, was the basis of five prior films: Enoch Arden, Die Toten kehren wieder - Enoch Arden, and D.W. Griffith's Enoch Arden: Part I, Enoch Arden: Part II, and Enoch Arden. Those films adhered to Tennyson's poem. But in My Favorite Wife, Something's Got to Give, and Move Over, Darling, only the basic idea of a spouse who returns is kept, with the spouse presumed lost now being the wife.
