I’m curious as to how you interpret it then. Do you see it as Kirk really believing he is stranded?
No, I believe that he tried to delay Khan (and buy Enterprise some time) by taunting him in the hopes of drawing him down to the asteroid, but it didn’t work and, after all the trauma Kirk had recently witnessed, the frustration and anger got the better of him for a few moments and he had an altogether normal and human moment of genuine fury. It doesn’t have to be (and is not improved by being) anything more than that.
I did a detailed analysis of the sequence in the film (or at least the DVD version in my possession) in an earlier thread, but just for laughs this time I dug out my copy of the novelization, by Vonda McIntyre. In the relevant passage, Tyrell has just killed himself instead of obeying Khan’s order to kill Kirk and Chekov has managed to barely fight off the Ceti eel. Khan starts to steal the Genesis Torpedo and Kirk tries to blast it with a phaser before transport is complete but cannot since David Marcus is in the way (this was acted out in the film but not, I thought, very clearly). Then this passage:
Underline emphasis added. I see nothing in this and nothing was mentioned in the DVD’s director commentary to suggest “fake anger” was ever an intention on the part of the film’s writer, director or William Shatner. If someone knows where I could see a shooting script that lends some support to the idea (which I didn’t hear about until at least 20 years after the film’s release), I’d like to see it, but I’d likely still reject it, not least because it robs the Kirk character of a significant dramatic moment that ties in nicely with the movie’s theme of the things we lose as we age.
I thought it was in the novelization, but I can’t find my copy. So I’ll retract that part of the post, but I stand by the rest of it, as more elegantly described by Brian Ekers above - even though Kirk knew he was going to be rescued shortly, he still had enormous frustration and anger towards Khan at that moment - ship horribly damaged, lab full of people dead, at least one death on his own ship, who just happened to be the beloved teenage nephew of one of his best and oldest friends, another Starfleet officer just suicided to save Kirk’s life, Chekov’s fate unknown, just found out he has a son - yeah, Jim Kirk wasn’t cool and collected.
Here’s some information on Earthly radiation damage. Looks like 30+ Gy causes almost immediate symptoms. For all I know, Warp drives might produce radiation that is much more potent (anti-protons, anyone?).
as to the infamous Khan scream - Kirk knew that Enterprise would be repaired (to a degree) within a shorter time frame - he did not know if Khan would find or destroy her before it was done. Enterprise managed to stay hidden during the intervening time frame.
He was trying to goad Khan to act rash and either beam him (kirk) to Reliant or Khan down there - it was a gambit that did not work.
Later (2 hours) - after enterprise is repaired and Kirk is back on board - Kirk again goads khan, and this time it does work.
Also, that’s the effects of radiation on human physiology. The effects of radiation on Vulcan physiology is pretty much up to the writer’s imagination.
I agree with this except for this point. Kirk has previously ordered Spock on suicide missions before, and presumably would have again had he known what was happening. In the episode “The Immunity Syndrome”, someone needs to pilot a shuttle into the giant space amoeba to figure out how to kill it. Spock and McCoy argue about who will fly the shuttle. Kirk tells Spock: “I’m sorry”, and McCoy gloats because he thinks he gets to go. But Kirk stops McCoy, because Kirk has just ordered Spock - as the best qualified person to save the ship - on a mission of certain death.
If anything the movie writers give us a bit of a cop out. Which is the better ending? Kirk learns the meaning of sacrifice because Spock knowingly chooses his death. Or Kirk learns the meaning of sacrifice because he orders Spock to his death, and finally for once, isn’t let off the hook.
I kinda gathered Kirk felt like Charles Darnay after Sydney Carton knocks him out to take his place at the guillotine.
Yet Spock’s final words are even better and more moving than Carton’s. So many feels. Take that, Dickens! 
Even if the lines got transferred to Kirk (dialog stealer!) it’s as if he is saying them about/for Spock.
We need more sci fi movies with this much depth! (and they didn’t even give a credit to Dickens - not even an “additional dialog by”.)
Apropos of fuck-all, I remember that for years I was confused about a 1959 Warner cartoon called A Witch’s Tangled Hare, which very loosely adapts MacBeth and has a Shakespeare-like character wandering through and taking notes. When Bugs Bunny finally talks to him, he admits that’s he’s not Shakespeare; his name is actually Sam Crubish.
For a long time afterward, I somehow thought that character’s name was Sam Taylor, the “additional dialogue by” guy from 1929’s The Taming of the Shrew and the joke was a reference to a longstanding Hollywood legend. When I rewatched the cartoon much later on (this one doesn’t seem to get as much airtime as other, possibly more kid-friendly works), I was left wondering - who the hell, if anyone, is Sam Crubish?
Is Captain Archer really Sam Beckett as a Leap In?
And would Captain Quantum be in Ziggy’s holding cell?
.
Sam Beckett leapt into a Federation starship Captain, and has absolutely no fucking idea what to do.
Well now he’s leapt into an NCIS agent - In New Orleans - and he still doesn’t know what to do.
Drink heavily, fit right in.
More tranya…?
Romulan Ale.
Quark got me a price on fifty cases.
Note to the Galley - Romulan Ale no longer to be served at diplomatic functions.
That’s an outrage!
The Captain was obviously not in his cups when he said that, poor man.
