The lighthouse in this film is the Angel's Gate at Los Angeles Harbor. It stands at the end of a 1 3/4 mile stone breakwater, and went into service in 1913. It was usually manned by four members of the Coast Guard from then until it was automated in 1973 when a modern searchlight (called an aerobeacon) was installed and the wooden structure surrounding the catwalk was removed. All of the buildings surrounding the lighthouse have also been dismantled. The height of the light is 73 feet (22 m). Its distinctive and unique green light has also been converted to a solar power source. The large fourth-order Fresnel lens of the light seen in this picture has been put on display at the Los Angeles Maritime Museum in San Pedro, California.
By the stylized "H" on the radio equipment and speaker in the lighthouse it indicates it was made by the Hallicrafters Company of Chicago, Illinois. It was in business from 1932 until 1966 when it was acquired by what is now Northrup Grumman.
Ernest Gold, who won the Academy Award for Best Music, Scoring of a Dramatic or Comedy Picture, for Exodus (1960) as well as four other Oscar nominations, is credited for the music for this movie.
This film had its earliest documented telecast in New York City Thursday 20 January 1949 on Film Theater of the Air on WCBS (Channel 2), followed by Los Angeles Tuesday 8 November 1949 on KTTV (Channel 11).
