People,
As I'm sure some of you know, one of the first choices to play Kruge was Edward James Olmos. I do think they made a good choice with Christopher Lloyd. My only problem was, from time to time, if you closed your eyes he sounded like Reverend Jim in command of a Klingon bird of prey! He sounded better when speaking his Klingonese lines, actually.
I do think his somewhat bombastic delivery did set the standard for future Klingon performances, like those of Gowron, Duras, Martok, even Worf. And of course, TSFS also greatly influenced the depiction of Klingon ships from then on, with birds of prey forming the bulk of many fleets we've seen, as well as the hulls turning from the more familiar grey-white to green.
My favorite moment is when Kruge realizes Kirk has tricked him into beaming his men aboard a ship about to explode, and he bolts up and shouts, "GET OUT! GET OUT OF THEEEERRRREE! GET OUTTTT!" It's one of those, "We got you, bastard" moments in movies I love!
