Principal photography began in Oct 1917, as indicated by the 3 Nov 19 Moving Picture Weekly, the official newsletter of Universal Film Mfg. Co. Because the producers were unable to find a suitable lighthouse on the Southern California coast, Universal’s technical department was assigned the construction of a “habitable and sightly” lighthouse, along with an adjacent cottage surrounded by trees, shrubs, and a white picket fence. Although the lighthouse was completed in a reportedly brief amount of time, it was able to withstand the weight of its human occupants. The close of production was announced in the 1 Dec 1917 Moving Picture Weekly. Child actress Elizabeth Janes was credited with giving swimming lessons to Zoe Rae, the film’s seven-year-old costar, known as "the Universal baby." The feature marked Zoe Rae’s second role alongside actors Gretchen Lederer, Winter Hall, and Harry Holden, with whom she had appeared earlier that year in The Cricket (1917, see entry). Another child actress, Janethel Monahan, was listed as a cast member in the 1918 Motion Picture Studio Directory.
