In the book he said the quote last. Which made the guy mad, the mouth of Sauron. I found the source from Quora website, been ages since i read LOTR in Norwegian
"Get you gone, for your embassy is over and death is near to you. We did not come here to waste words in treating with Sauron, faithless and accursed; still less with one of his slaves. Begone!’ Then the Messenger of Mordor laughed no more. His face was twisted with amazement and anger to the likeness of some wild beast that, as it crouches on its prey, is smitten on the muzzle with a stinging rod. Rage filled him and his mouthslavered, and shapeless sounds of fury came strangling fromhis throat. But he looked at the fell faces of the Captains andthe black gate opens their deadly eyes, and fear overcame his wrath. He gave a great cry, and turned, leaped upon his steed, and with his company galloped madly back to Cirith Gorgor."
