The future Data has gray hair, many cats (ironically, Brent Spiner hates cats) and can even use contractions now. He also seems emotional, suggesting he implanted Dr Soong's emotion chip, as in Star Trek: Generations (1994).
This episode won the 1995 Hugo Award for Best Dramatic Presentation, the first "ST:TNG" episode to do so since Star Trek: The Next Generation: The Inner Light (1992) (1993). They are, in fact, the only two TNG episodes to have won this award.
Ships can go up to warp 13 in the future. This somewhat contradicts Star Trek: Voyager: Threshold (1996), where warp 10 was established as the barrier between warp and transwarp. However, this barrier was never again mentioned afterwards and may have been a one-off idea by the writers; or the warp scale has once again been changed in the future, just as it had been during the transition from Star Trek (1966) The Original Series to "Star Trek: The Next Generation".
Picard's captaincy of the Enterprise is approved by Admiral Nora Satie. Satie made an appearance in Star Trek: The Next Generation: The Drumhead (1991), where she and Picard were at odds with one another over her paranoid belief in a Starfleet conspiracy.
Cambridge still exists in the 24th Century, where Data now occupies the Lucasian Chair, previously held by scientific giants like Sir Issac Newton and Stephen Hawking. Data played poker with holographic versions of them in Star Trek: The Next Generation: Descent (1993).
Production on Star Trek: Generations (1994) began while the episode was made. The scenes filmed were on the Enterprise-B set. After production wrapped on the series finale, the cast got a ten-day break before jumping back in to work on the film.
Picard gets the idea for the tachyon scan from the future Data, and then suggests the same idea to the past and present Data. The same applies to the tomographic imaging scanner, but in reverse: the past Data suggests it to Picard, who passes on the idea to the present Data.
When this episode was written, the drafts would often get mixed-up with those for Star Trek: Generations (1994). Meaning the stories would sometimes get confused with one another. The writers later admitted that of the two, All Good Things... was the superior effort.
Data begins a long and tedious rant about the meanings of "burn the midnight oil..." at one point in the past. This is reminiscent of earlier seasons where Data would go on at length about something and have to be stopped.
There are parallels between this story and that of a 1979 Doctor Who (1963) episode, "City of Death," co-written by bestselling author Douglas Adams. Both feature a notion of time-splintering, the prevention of life evolving on Earth, and a scene of contemplating primordial ooze that will become the human race.
The warp 5 speed limit (Star Trek: The Next Generation: Force of Nature (1993)) has obviously been abolished in the future, since ships can go to warp 13. This suggests that a method to stop warp drive destroying space has been found, although it is never brought up.
The Romulan commander used, Tomalak, had not appeared since Season 4. This was the only time that Andreas Katsulas appeared on Star Trek during his run as Ambassador G'Kar on Babylon 5. He later played another character on Star Trek: Enterprise after the end of Babylon 5. With Colm Meaney guest-starring in this episode, this was a rare occurrence that regulars on competing shows Babylon 5 and Star Trek: Deep Space Nine appeared in the same episode during the run of both shows.
There are some similarities to Q's last appearance in Star Trek: The Next Generation: Tapestry (1993) in so far as Picard is sent into the past and back to the present. The circumstances as well as the conclusion, however, are rather different.
A future rendering of the Caduceus can be seen in several places on the bridge of Beverly's ship, erroneously used for the Greek symbol for medicine. In actuality, the rod of Asclepius (one snake, one staff, no wings) is the correct Greek symbol for medicine.
The footage of the 2364 Riker reporting is a shot taken from "The Arsenal of Freedom". The man featured behind Riker is Paul Rice, played by Marco Rodriguez, or at least the holographic version from the aforementioned episode. Rice was digitally removed when the episode was remastered in 2014.
When Picard and Geordi visit Data at his house, Data asks Picard how long it has been since he has seen a doctor for his Irumodic Syndrome, to which he replies "a week, they prescribed Peridaxon". He pronounces it much like the word PARADOX. Perhaps this was an early clue to the key to saving humanity. In the end Q states that Picard has shown he can expand his mind, specifically when he realizes the the time PARADOX related to the spacial anomaly.
Early versions of this story included the Borg attack at Wolf 359 as a fourth main timeline, with Picard appearing as Locutus. According to Brannon Braga, Hugh would have appeared as well, helping to rescue Picard from the Borg in this timeline.
USS Enterprise-D's possession of a cloaking device, gives a hint that the Treaty of Algeron's agreement for the Federation to not use any cloaking devices may no longer be in force in the alternate timeline of the anti-time future in 2395.
The bird sculptures in Q's court room previously appeared in the pilot episode "Encounter at Farpoint". They can also be seen in Karnas' office in the first season episode "Too Short a Season" and in the bar on Qualor II in the fifth season episode "Unification II".
The console Romulan Commander Tomalak leans over to address Picard through the viewscreen is a reuse of a stock set element that previously appeared as a central console on the mercenary vessel's bridge in "Gambit, Part I" and "Gambit, Part II".
The notion of being "unstuck in time" was also used by author 'Kurt Vonnegut, Jr.' in his novel 'Slaughterhouse-Five', whose protagonist, Billy Pilgrim, also "bounces" between three periods of his life.
Worf and Deanna's romance, hinted at throughout the season comes to its fruition here. In the future we see, Deanna is dead, and she never got together with Worf. Probably because of Riker, who is clearly uncomfortable with it when he sees the two of them together in the present. This drove a wedge between them. The circumstances of her death are not known. The relationship between Worf and Deanna seems to have petered out because there is no mention of it in the films or Star Trek: Deep Space Nine (1993) where Worf eventually became a regular. The writers of DSN came up with an explanation for why Worf and Deanna parted, but never found a suitable place to fit the exposition on screen.
The first time Picard comes to the senior staff poker game. An alien duplicate of Picard did it in Star Trek: The Next Generation: Allegiance (1990) but didn't join in. In both episodes, a crew member says Picard was always welcome to join. Also the only time where the entire senior staff play the poker game all at the same time.
Nurse Ogawa's pregnancy, last mentioned in Star Trek: The Next Generation: Genesis (1994), resurfaces here. In an alternate timeline, the tachyon pulse from the ship's deflector responsible for the anomaly causes her to have a miscarriage. But once the anomaly collapses and time resets itself, this thankfully never comes to pass.
In the future, Picard and Beverly get married and then divorced. Although a possible romance is hinted at before the end, it was never followed up in any of the films - perhaps to avoid the future seen here.
After its initial release as a 2-hour season finale, this episode was edited for syndication into two hour long episodes with some scenes deleted. These include: Geordi telling Picard about his wife Leah and his children while tending to the vines. A part of the exchange between Ambassador Picard and Worf at their initial encounter (after Worf has cursed until the moment he allows the Pasteur to cross the border). Deanna telling Picard about her former relationship with Riker, and Picard then trying to order a cup of Earl Grey. Part of the exchange between Picard and Tomalak. Beverly Picard doubting the reality of her ex-husband's claims during their discussion in her ready room. An important exchange on the Pasteur between Picard and Q, in the guise of an old man. Beverly Picard ordering Worf to signal their surrender during the Klingon attack. A crewman on the "future" Enterprise reporting that the cloaking device isn't functioning. Dr. Crusher tending to Geordi and Ogawa, before Picard enters sickbay. Parts of the scene where Q takes Picard to prehistoric France. A scene on the "future" Enterprise of Picard wandering through the ship and asking a low-ranked crewman the way to Ten Forward. And Picard thanking Q for his help at their final exchange. Also, a short recap "Last time on "Star Trek: The Next Generation" was added to the beginning of the second part in place of the teaser.
Another future development is that the Klingons have conquered the Romulan Empire, and the Neutral Zone has been dissolved. It seems the alliance between the Federation and the Klingon Empire has also ended, perhaps because the Empire is eager to expand its territories. This is a plot line explored for a time in Star Trek: Deep Space Nine (1993), when, thanks to Dominion interference, a multi-sided conflict erupts.
