The last-ever episode of this series is another oddball segment, following the "musical" episode, "All The Old Familiar Faces", and the science-fiction/fantasy episode "LA 2017". It largely consists of flashbacks to the days of the Old West, with most of the leading actors playing two parts, one in the present and one in the past.
This was Robert Stack's final appearance in the series.
The opening credits of this episode are written (in a different type-face than usual) as the pages of a book. At the end, the last page of the book reveals the one word "Fine" (the Italian for "The End"), after which the end credits come up in the usual fashion.
Joseph Calvelli, the scriptwriter of this episode (a somewhat more light-hearted one than usual), also makes a rare television acting appearance in a supporting role.
According to scriptwriter Richard De Roy, the character of "Hallie Manville" was intended to become a regular series character, a replacement for the "Jeff Dillon" character played by Anthony Franciosa, who was fired from the show. However, the series was cancelled at the end of its third season (there were just a few more segments aired after this one) and "Hallie Manville" was never seen in it again.
Joan Crawford had been approached to play "Victoria Stuart" in this episode, but illness caused her to bow out. She was replaced by Mercedes McCambridge - ironically, as the two actresses disliked each other intensely after working together on the 1954 film "Johnny Guitar".
Robert Wagner, playing "David Corey", appears as one of several replacements for Tony Franciosa's "Jeff Dillon" character. Wagner had appeared previously in the series, but as a different character.
The opening episode credits, which occur after a prologue in which Glenn collapses at the wheel of his car, are written in a different type-face than is usual in the series - the new type-face suggests a futuristic computer print-out. The credits at the end of the episode are as normal, however.
The script for this episode was written by Philip Wylie, a well-known science-fiction writer of the 1930s and 40s. It was his only script contribution to the series, and was his first writing for television in fifteen years. It also marked his farewell to the medium; he died of a heart attack some nine months after this famous episode was first aired.
This was Peter Falk's only appearance in the series, as a replacement for Tony Franciosa's "Jeff Dillon" character.
The eccentric but very successful artist Rex Dakota seems meant as a parody of Andy Warhol.
Although this episode marked the end of Tony Franciosa's appearances in this series, he and co-star Gene Barry were reunited later in the decade, when both had cameo roles in the mini-series, "Aspen", also known as "The Innocent And The Damned". This was also produced by Universal.
This segment marked Tony Franciosa's farewell to the series. Universal tired of his constant quarrels with the producers and fired him quite early into the filming of this third series, although the episodes he had completed were spread out over many weeks. Instead of hiring a permanent replacement, the show featured various guest actors playing other journalists in the employ of Howard Publications, who variously starred in episodes originally planned for Franciosa.
This was the most star-laden story in the entire three-year series, with many famous Las Vegas entertainers appearing briefly as themselves in addition to the usual roster of big-name guest stars in acting roles.
The five-person singing group serving as a chorus to the action in this episode (known as "The Third Eye") comprised the twin sisters Alyce Andrece and Rhea Andreca (real name: Rhae Andrece); James J. Joyce; Jon Joyce; and Randy Joyce.
The title is taken from the famous old song, "I'll Be Seeing You", which was a huge popular hit in the 1940s and was written by Irving Kahal and Sammy Fain. However, there is a new song called "All The Old Familiar Faces" featured in the episode.
In the small but crucial role of the murdered Native American, Little Bear, George H. Burdeau made what seems to have been his only TV acting appearance ever.
The second and last of Robert Culp's appearances as "Paul Tyler", a replacement for the Tony Franciosa character of Jeff Dillon.
This was the first TV writing credit for the novelist and poetess Wanda Coleman. Her only other TV credit, some five years later, was an episode of Starsky And Hutch.
This episode was the final credit for veteran cameraman Andrew J. McIntyre; he died some four months before it was first aired.
