Star Trek IV: The Voyage Home

Visible crew/equipment: During a close up of the police officer's sunglasses, when Chekhov is asking for directions to Alameda, some crew are visible in the left lens. They are a line of people trying to stay out of the camera. (00:43:30)

Continuity mistake: In the scene where Spock gets confronted after swimming with the whales: you can easily see before he puts on a robe, that his clothes are completely dry, yet he had just been swimming in the shot a moment earlier.

Visible crew/equipment: At approximately 01:32:50 on the Blu-Ray, you can see a diver releasing the mechanical whales. He is on the far right side of the screen, you can make out his head, body and left hand. He is visible for a good 8-9 seconds. If you have a different media source, it's during the Bird of Prey decent. You see a closeup of Kirk, followed by a closeup of Uhura and Gillian, then a close up looking down on the harpoon. It's in the following scene. (01:32:50)

Continuity mistake: In the scene with Kirk and Spock walking the marina green under the Golden Gate Bridge, the leading shot shows blue sky. As the camera changes angles, the background changes to completely fogged in. Not shot on the same day.

Factual error: At two points in the film, the Klingon vessel Bounty traverses the distance from the Earth to the Sun at maximum speed, in excess of Warp 9. The latter sequence requires about 111 seconds from the time Sulu says "Aye sir, warp speed" until they reach the Sun. While there is no real science behind Star Trek's "warp technology, " the Starfleet Technical Manual provides a formula for calculating warp speed, whereby Warp 9 translates to about 136 MILLION MILES PER SECOND. The Earth is only 93 million miles from the Sun. In the apparent time that it takes the Bounty to reach the Sun, a starship traveling at such ferocious velocity would already be outside of our known solar system and deep into interstellar space.

Continuity mistake: The crew wrote 'HMS Bounty' in large red letters on the side of the Klingon Bird of Prey, but in all subsequent flying shots, the large red writing is never seen again. It's not burned off as you only get heat entering the atmosphere if the speed is sufficient, and it's not wind resistance either, because the lettering is missing just after they take off.

Audio problem: When Gilliam slams on the brakes, the tires make a screeching sound, but the wheels come rolling to a stop, ergo do not skid. (00:56:50)

Plot hole: If the Bird-of-Prey went to warp speed right after the whales were beamed up the ship would have already been so far away from Earth it would have been on its way back towards the sun, yet minutes later the ship is shown leaving the Earth, still at warp speed.

Continuity mistake: When we first see the whale pen it is divided from the sea by a concert wall with double gate in the middle, but when the whales are released most of the wall and gates are missing.

Revealing mistake: When Kirk and crew flee the hospital McCoy bumps a man with his leg in a plaster cast. Look closely at the cast - it is fitted over his PJ's leg like a boot, plaster casts are never fitted over clothing.

Factual error: As they descend into the park, Uhura gives a bearing and range of 283 degrees, 15.2 kilometers to the whales, which are supposedly in a marine park in Sausalito. 283 degrees would put you in the Pacific Ocean, because Sausalito bears around 360 degrees from the park. Uhura gives a true bearing to the whales, since a relative bearing would be useless once the crew leaves the park.

Spock: They like you very much, but they are not the hell "your" whales.
Dr. Gillian Taylor: I suppose they told you that.
Spock: The hell they did.

Question: When Kirk and McCoy try to rescue Chekov at Mercy Hospital, Kirk removes the 20th Century medical team into an adjacent room and uses his phaser to instantly fuse the metal door lock. The medical team cannot directly see Kirk do this, as they are visibly several feet away on the other side of the door. It's also safe to say that the medical team has never seen a phaser and can't comprehend its function or capabilities. As Kirk turns away from the door to rejoin McCoy, the trapped medical team only then rushes up to the door, and the trauma surgeon exclaims, "He melted the lock!" However, it seems that you'd have to laboriously dismantle the doorknob to determine that the lock's internal components were fused. So, how did a 20th Century surgeon deduce at a glance that Kirk had somehow melted the lock?

Charles Austin Miller

Answer: The lock, and the area around it, would have become hot as a result of melting the lock. The hospital staff would then jump to the conclusion that the lock was melted. The real reason they mention it, however, is so the audience knows what he did to the lock.

But you would think, if the doorknob was still searing hot two seconds after being fused, that the first thing out of the surgeon's mouth would be a scream of pain, rather than "He melted the lock!"

Charles Austin Miller

Answer: The knob would have been super-heated by the phaser blast. Enough that it could be felt without touching, and he simply could have come to the conclusion that a metal object that hot would likely have its internal components melted without a systematic analysis of the doorknob. He's also a surgeon and needs his hands. He wouldn't last long at the job if he was someone who went around putting his hand on glowing-hot doorknobs.
