Bill Bixby was fond of bringing old co-stars to guest-star in his new series. Here, a blonde middle-aged woman, who was a recurring extra throughout his series The Magician (1973), can be seen, and for the first time heard, at the very final scene: she is driving a van and asks someone for directions.
The story bears a loose resemblance to alleged sightings of Bigfoot.
William Lucking and Lance LeGault both played pursuers of "The A-Team": Colonels Lynch and Decker, respectively.
The title is a play on "The Amityville Horror." Granted, the movie would not be released until 1979, but the book was released in September of 1977.
David's pseudonym in this episode is "David Barton." This is a reference to fellow Marvel superhero Clint Barton/Hawkeye.
