At 59 minutes, "Where the Dead Are" is the longest story in the history of "The Twilight Zone".
This is the only "Twilight Zone" episode or film not to be released on DVD in the United States. However, it has been released on DVD in the United Kingdom.
The lady in the theater that Amy Irving (Melissa Sanders) talks to is played by her real life mother, Priscilla Pointer. Pointer previously played Miss Cox in the segment "Kick the Can" of Twilight Zone: The Movie (1983), which was directed by her former son-in-law Steven Spielberg.
Dr. Jeremy Wheaton quotes the following line from "Julius Caesar" Act II, Scene II: "Of all the wonders that I yet have heard, it seems to me most strange that men should fear, seeing that death, a necessary end, will come when it will come." The same line was quoted by President Abraham Lincoln (Austin Green) in The Passersby (1961), another story set in the aftermath of the American Civil War written by Rod Serling.
