Gothmog was truly chilling to me. I assumed, perhaps wrongly, that he was an orc and in Peter's rendition of him I thought to m yself he must have been horribly tortured to look like that. He seemed to take more than the usual delight in the torment and murder of Men and elves. He just electrified the scenes he was in, well the actor did. He was stupendous.
By the way the actor, was he not two other characters as well? I thought he was the orc I despised the most, the one who killed dear Boromir, and then someone else? I really cannot recall.
