In this film, Deneen starred his wife and three sons (all uncredited), after he'd arranged a trade with Italian Lines for free passage for his family in return for a film about the liner S.S. Leonardo Da Vinci. Deneen states that 90% of the shots were filmed on the Da Vinci, and another 10% were filmed aboard the S.S. Michelangelo on his return voyage. The film is a remarkable children's film as well as serving as an important document of one of the most advanced ocean liners of its day, now scrapped.
