Corrected entry: When Spock analyzes the call of the probe and compares it in a phylum search, he's presumably interfacing with the Federation memory bank as mentioned in Sulu's pre-launch status. However, the alien probe was disrupting all power and communications in the vicinity of Earth. It's extremely unlikely the ship could've interfaced with the Federation memory bank at the time of that search. (00:24:55)
Corrected entry: Given the distance the probe must have traveled before it reached the Neutral Zone it would had to have encountered starships long before encountering Saratoga, so why didn't Starfleet know about the probe before Saratoga was neutralized?
Corrected entry: Kirk conveniently has the broken pair of reading glasses with him that he sells to the antiques dealer in 1986. The glasses were damaged at the end of "Wrath of Khan" which means he would have no further use for them, but for some reason he would have had to have them on him during the events of "Search For Spock" for them to be stranded with him on Vulcan, just as he and the crew were at the beginning of the movie.
Corrected entry: When the 'Bounty' materializes above the whaling ship, the close-up of the captain and navigator frantically turning the ship around reveal that only the captain has his hands on the wheel; the navigator is flapping his hands in the air rather than helping turn the wheel of the whaling ship.
Corrected entry: When the Bounty takes off from Vulcan and flies away, no shadow is visible despite the fact that it is a very sunny day. (00:16:20)
Corrected entry: In the scene where the commander of the navy ship is on the phone, first he is told that nobody knows why they are having a power drain. Then suddenly he makes a call and says that there is an intruder. There is no way he or anyone else could have suddenly known there was an intruder, because nobody had physically seen or detected Chekov and Uhura yet. And there is no "modern" technology that could drain power from the reactor so there was no reason to equate the power drain to an intruder alert.gawdsmak
Corrected entry: In the scenes where Kirk's communicator goes off (like during dinner with the scientist lady) to simply inform him that Chekhov is about to beam to the ship, this completely goes against his first orders given before they landed that communicators should only be used in case of emergencies.gawdsmak
Corrected entry: In the scene where they spray paint the ship, you can see the ship is suspended on landing gear. then later when it lands in the park cloaked, the special effect shows the garbage can being compressed under the ship, and the outline of the entire ship indenting into the ground, as if the entire ship is making contact with the ground,but really only the small area of the landing gear should be compressing the ground and only at certain points.gawdsmak
Corrected entry: Dr. McCoy advises Scotty about giving the manufacturer the formula for the transparent aluminum for fear that it would alter history. Yet he himself gives the elderly woman in the hospital the pill that grows her a new kidney, hence future medical technology in the hands of 20th century physicians, something doctors and others would definitely be studying after the woman's miraculous recovery.jbrbbt
Corrected entry: It is established at the start of the movie that the Klingon Bird of Prey is the same one that they flew to Vulcan in Star Trek III: Search for Spock. The bridge of the ship however is totally and utterly different to the one shown in the previous movie. There can be no claim to suggest they remodelled it in their time on Vulcan, because everyone still uses the controls with a degree of caution, which they wouldn't do if they modified it to suit their needs.GalahadFairlight
Corrected entry: The humpback whales are about to be returned to Alaska for release back into the wild. Dr. Gillian Taylor tells Kirk and Spock that Gracie is "very pregnant." In that event, the whales should be released in Hawaii instead of Alaska. Humpbacks give birth in warm, south Pacific waters during the winter and later migrate north for summer. (01:04:30 - 01:21:20)
Corrected entry: Immediately after the whales' transponders are located in the Bering Sea, Gillian can be seen mouthing, "How can you do that?" without sound, then she is immediately seen and heard giving the same line from another camera angle.
Corrected entry: When the crew starts to evacuate the Bird of Prey from the ship's hatch, the sound stage wall is easily visible.
Corrected entry: In the chase scene where Checkov is being rescued from the hospital, there is a shot where the crew bursts through some doors and knock over a man on crutches wearing a cast. As he falls, Bones grabs him and the camera pans off. Once the camera pans, you can hear Bones say to him, "Great shot!" This was on the video version of the movie. I haven't seen the DVD.
