Star Trek IV: The Voyage Home

Corrected entry: Starfleet has serious regulations on bringing future technology to inappropriate time periods (which is why the Bird of Prey remained cloaked during it's time in 1986). Chekov being fully aware and considerate of these regulations, considering he has been in Starfleet for about 20 years should have never tossed the Klingon phaser (23rd Century technology) at the navy officer (20th Century person) with full knowledge that he'll never be able to retrieve it. He is too smart for it to have been panic.

Correction: Maybe a bad error in judgment, but a character mistake, not a movie mistake.

Correction: First off, the men interrogating him do not appear to be Navy officers but rather federal agents (FBI, CIA, etc.) The guy asking the questions has some idea of what the phaser is supposed to be, "Make nice, give us the ray gun" so he either deduced that or as is common in interrogations, they're asking the same questions over and over. The interrogators obviously don't believe a word of what Chekov is saying, hence why the one agent tells him, "Go ahead, stun me."

Visible crew/equipment: In the scene where Sulu flies the helicopter and accidentally turns on the windshield wiper, look closely at the bottom of the wiper and you can see the crewman's finger manually moving the wiper. (01:18:55)

Spock: Your use of language has altered since our arrival. It is currently laced with, shall we say, more colorful metaphors, "double dumb-ass on you" and so forth.
Kirk: Oh, you mean the profanity?
Spock: Yes.
Kirk: Well that's simply the way they talk here. Nobody pays any attention to you unless you swear every other word.

Trivia: The aircraft carrier that Uhura and Chekov find is actually the USS Ranger, standing in for the USS Enterprise. The Enterprise was at sea during filming.

More trivia for Star Trek IV: The Voyage Home

Question: What exactly was Scotty's reason as to why giving the Company boss the formula for the one inch glass wouldn't alter the future? He gave a brief response, but I honestly can't think of any reason why it wouldn't do any future damage.

Gavin Jackson

Chosen answer: Scotty says "Why? How do you know he didn't invent the thing!" If the man was in fact the inventor, this would only cause a slight causality loop problem - he "invents" it because they gave it to him, but they only know it because he "invented" it. However, since Sulu said earlier in the movie that it was about 150 years too early for transparent aluminum, it would seem they do know this, so it wasn't a smart thing to do. Of course, the real flaw in the plot is that they need the tank to be transparent at all.


Answer: They only give him a schematic of the molecule. The man even says, "It would take years to decipher the matrix", or something like that.
