And who isn't impressed with Montalban's creepy, lightly oiled chest and awesome geriatric-mullet? Dude, he was 61 when he did this film. Not bad, Ricardo. Stayin' fit, there.
Not to be outdone by William Shatner's (Kirk) awesome hairpiece and visible man-girdle seen beneath the santa-claus red polyester double knit Starfleet uniforms. And who decided said uniform pants would look better with the pant legs tucked INTO the boots? A 23rd century fashion genius, that's who.
The doctor, Bones, does nothing but stand on the bridge and say pithy things like "Dammit Jim, (insert grousing item here)."
Really, the best best line ever in this movie is the most impossible to deliver. And Montalban does it in accented fabulousness as he commits 100% to his crazy character: "He tasks me. He tasks me and I shall have him! I'll chase him 'round the moons of Nibia and 'round the Antares Maelstrom and 'round perdition's flames before I give him up!" (Anyone read Moby Dick? This is an awesome allusion.)
The whole thing is a study in fatal flaws. Khan: focus on revenge. Kirk: reliance on the belief that he is invincible.
So remember: Don't maroon a genetically-altered, long-lived evil genius with a long time to fester about the wrongs done to him, and then return to said maroon location thinking you'll get away unscathed. Worms in the ears, anyone?
As a last parting comment, I shall simply leave you with: "KHAAAAAAAAN!"
