The construction worker who was trapped under the boat was trapped under the PT-73 boat, which was the PT boat from the McHale's Navy TV series.
The accidental shooting couple were played by Olympic swimmer Mark Spitz and his wife, Suzy Spitz. It would be her only dramatic television appearance, and she was not pregnant at the time. The Spitz would later have two sons, born in 1981 and 1991.
The station is called to rescue a man trapped at "World Pictures Studio," and the location is given as the intersection of "Pickford and Douglas Avenues" - a reference to silent movie stars Mary Pickford and Douglas Fairbanks.
