The baby is played by Olive Sturgess's nephew, Leonard Sturgess.
Later that same year, Nick Adams and guest star Myron Healey would work together again on screen in the episode of Wagon Train (1957) titled The Traitor (1961). Within the next decade, Healey and Adams would also both later star in separate Kaiju films opposite some of Toho Studios' most popular giant monsters--Healey in Varan the Unbelievable (1962) (with the first of few screen appearances by the title monster) and Adams in both Frankenstein vs. Baragon (1965) (US title: "Frankenstein Conquers the World," featuring Toho's Frankenstein opposite Baragon) and Invasion of Astro-Monster (1965) (US title: "Monster Zero," featuring Godzilla, Rodan and King Ghidorah). All of those monsters and more (except for Frankenstein) would all appear together later in the epic Destroy All Monsters (1968) (US title: "Destroy All Monsters").
