Upon first meeting Steven Spielberg, Joan Crawford was less than impressed. She called Sid Sheinberg, then head of Universal Television, and told him to replace Spielberg with a better director or she would quit the series. Sheinberg told her in no uncertain terms that the studio would back Spielberg over her, as she had not acted on television in years and was at the time the Chairman of Pepsi-Cola, and Universal was confident in Spielberg's abilities. She subsequently treated him with the utmost respect, and the two continued to correspond until her death.
The "Eyes" segment was Steven Spielberg's professional debut as a director. This was quite an auspicious beginning, considering that he was to direct screen legend Joan Crawford, winner of an Academy Award who had been acting in films since 1925.
This is second of two Joan Crawford vehicles in which she plays a woman who undergoes surgery to regain her sight. In 1952's This Woman Is Dangerous, she played a similarly sight-impaired character who has a risky eye operation.
In the first segment, in the scene in which Roddy McDowall shouts, "What in God's name is happening?" the sound track was faulty. During editing, McDowell was no longer available, so director John Badham himself looped the line.
The segments "Eyes" and "The Escape Route" are based upon novellas Rod Serling wrote for the book "The Season to Be Wary" in 1967. Serling conceived of this series as a way to revive the anthology concept of The Twilight Zone (1959) with a fresh spin. Initially the series was to be called "Rod Serling's Wax Museum."
Richard Kiley was forty-seven when he acted in "Night Gallery". That would make him very much younger than the character he played--Strobe was a major general in the SS twenty-four years earlier, so he would have to be in his sixties at least.
The trivia item below may give away important plot points.
In "The Cemetery" segment, Gibbons mentions that Portifoy has bought 15 of his paintings. If each stage of Jeremy's rise from the grave is considered as a separate picture, the two series of paintings (that is, minus the original) add up to a total of 15.
