...Even though the fictional time span between Star Trek II:The Wrath of Khan and Star Trek V: The Final Frontier was less than one year, they were released five [sic. seven] years apart, in 1982 and 1989 respectively. Star Trek II:The Wrath of Khan was filmed in 1981, about 15 years after first season episodes like "Balance of Terror" and "Space Seed" were filmed, and Star Trek V: The Final Frontier was filmed in 1988, about 22 years after first season episodes were filmed..
1982 and 1989 are seven years apart, not five.
Oops! My mistake.
So the makers of Star Trek V: The Final Frontier might have assumed that since it was filmed 22 years after first season episodes were filmed, it should have a fictional date 22 years after the fictional date of the first season episodes. And I can't help thinking that it was really amateurish of them not to count the fictional time instead, and realize that Star Trek V: The Final Frontier should be no more than 16 years after "Space Seed" in fictional time...
How is it amateurish of them if the Trek timeline hadn't been explicitly nailed down at that point? STV was shot in 1988 and released in 1989. The first edition of The Star Trek Chronology was published on April 1st, 1993. In the absence of any other information, assuming it was more or less the same time gap for the characters that had been for the actors was a natural assumption.....
SHORT ANSWER:
JonnyQuest037 is wrong about the fictional time between those moves. The dates that were later arbitrarily assigned to the
Star Trek movies of the 1980s by the
Star Trek Chronology weren't needed to get a good idea of the fictional time elapsed between those movies. There was no absence of information.
LONG ANSWER:
In
Star trek II: The Wrath of Khan the Enterprise is taking cadets and trainees on a training cruise:
KIRK: Well, Mister Scott, are your cadets capable of handling a minor training cruise?
KIRK (OC): We've got a problem. Something may be wrong at Regula I. We've been ordered to investigate.
SPOCK: If memory serves, Regula I is a scientific research laboratory.
KIRK (OC): I told Starfleet all we had was a boatload of children but ...we're the only ship in the Quadrant. Spock, these cadets of yours, how good are they? How will they respond under real pressure?
At the end:
Captain's log, stardate 8141.6. Starship Enterprise departing for Ceti Alpha Five to pick up the crew of the U.S.S. Reliant. All is well. And yet I can't help wondering about the friend I leave behind. 'There are always possibilities' Spock said. And if Genesis is indeed 'Life from death', I must return to this place again.
Star Trek III: The Search for Spock begins with:
U.S.S. Enterprise. Captain's personal log. With most of our battle damage repaired, we're almost home. Yet I feel uneasy and I wonder why. Perhaps it's the emptiness of this vessel. Most of our trainee crew has been reassigned. Lieutenant Saavik and my son, David are exploring the Genesis planet which he helped create. And Enterprise feels like a house with all the children gone. No, more empty than even that. The death of Spock is like an open wound. It seems that I have left the noblest part of myself back there ...on that newborn planet.
Some of the trainees are still aboard as they approach Spacedock & Earth:
TRAINEE FOSTER: Sir, ...I was wondering. ...Are they planning a ceremony when we get in? ...I mean, a reception?
They return Spock to Vulcan at the end and Spock's body and katra are newly reunited in the very last scene.
Star Trek IV: The Voyage Home begins with the Saratoga meeting the whale probe and then Kirk's log entry:
Captain's log, stardate 8390. We are in the third month of our Vulcan exile. And it was Doctor McCoy with a fine sense of historical irony, who decided on a name for our captured Klingon vessel.
('HMS BOUNTY' is roughly painted in large red capital letters along the side of the Bird-of-Prey)
Captain's log. (continued) ...And like those mutineers of five hundred years ago, we too have a hard choice to make.
"In the third month" means between two and three months after their Vulcan exile began. Seemingly just a few days later the protagonists crash near San Francisco and release the whales.
After an unknown duration of time there is the trial and the Federation council makes a decision:
FEDERATION PRESIDENT: James T. Kirk. ...It is the judgment of this Council that you be reduced in rank to Captain, ...and that as a consequence of your new rank, you be given the duties for which you have repeatedly demonstrated unswerving ability. The command of a starship. ...Silence! Captain Kirk, You and your crew have saved this planet from its own short-sightedness ...and we are forever in your debt.
(prolonged applause and cheers from all those present)
After another unknown period of time Kirk and Co. approach their new assignment:
KIRK: My friends, ...we've come home.
(they approach a shiny new Constitution-class starship, NCC-1701A, a New Enterprise)
[Enterprise-A bridge]
SULU: Helm ready, Captain.
KIRK: All right, Mister Sulu, Let's see what she's got.
SULU: Aye sir!
END CREDITS
Star Trek V: The Final Frontier Opens with scenes on Nimbus III and at Yosemite on Earth, and then switches to the Enterprise in orbit:
[Spacedock]
SCOTT (OC): U.S.S. Enterprise, shakedown cruise report. I think this new ship was put together by monkeys. Och, she's got a fine engine, but half the doors won't open, and guess whose job it is to make it right?
[Enterprise-A bridge]
SCOTT: Borgus frat! 'Let's see what she's got' said the Captain. And then we found out, didn't we?
That sure sounds like Scott has been trying to repair the Enterprise since it got back from the shakedown cruise at the end of the previous movie.
SCOTT: All I can say is they don't make 'em like they used to.
KIRK: You told me you could have the ship operational in two weeks. I gave you three. What happened?
SCOTT: I think you gave me too much time, Captain.
So this indicates that it has probably been only about three weeks since they returned from the voyage at the end of the previous movie. And considering how many problems the new Enterprise has, that voyage should have been rather short.
Even allowing for the two time periods of unknown length during
Star Trek IV: The Voyage Home, it seems obvious that the four movies from
Star trek II: The Wrath of Khan to
Star Trek V: The Final Frontier happen in far less than one Earth year.
It seems to me that by 1988 it would have been easy for scriptwriters to play videotapes of the earlier three movies to remind themselves of various plot points, and obvious that William Shatner and Harve Bennett would have had a lot of experience making those three previous movies and could have remembered plot details.
Thus they should have noticed that Dar's "twenty years" doesn't agree with the length of fictional time elapsed since the first season of TOS, as I stated in my post number 599 on page 30 of this thread.
