In Adaptations
The Mouth of Sauron is featured in the 1980 animated version of The Return of the King produced by Rankin/Bass and was voiced by Don Messick. He rides out briefly with a single companion and makes no mention of Frodo's capture.
In the 2001-2003 The Lord of the Rings film trilogy by Peter Jackson, the Mouth of Sauron does not appear in the theatrical cut of The Lord of the Rings: The Return of the King, but he does appear in the extended version, riding out alone to meet Aragorn and his party. He is played by a virtually unrecognisable Bruce Spence, with the words lammen gorthaur (Sindarin for "Voice of the Dread Abomination" i.e. "Voice of Sauron") in Cirth runes written on his helmet. His helmet covers his entire face except for his mouth (which is inconsistent with the book, where Aragorn meets his gaze), which is horribly diseased and disfigured. His mouth is also disproportionately large, creating an unsettling effect. This change was made digitally, long after the footage had been shot. After Jackson rejected the idea of turning the mouth sideways to appear vertical on the face, the designers came up with the idea of rendering it twice as large as the original.
The extended DVD cast commentary mentions that Jackson considered different depictions of the character, such as having Kate Winslet (who starred in Heavenly Creatures, another Jackson film) play the role, partially to emphasise the temptations Aragorn was facing. When discussing Bruce Spence's costuming in the final version, the design team explained that their interpretation of the Mouth of Sauron was that he was something of a high-ranking priest in the Morgoth-worshiping cult that Sauron promoted in his domain. Therefore, combined with his role as an ambassador and herald, he has an ornate costume consisting of priest-like robes and stylized helmet which covers his entire face - including his eyes - except for his mouth. The design team speculates that he is probably blind, but his role as Sauron's "mouthpiece" is so specialized that this does not concern him. Further, his lips are cracked and blackened, with rotting teeth, to hint that Sauron's very words are so evil that simply repeating them causes his mouth to decay.
According to designer Walter Mahy, the original design for the Mouth of Sauron's costume had the helmet hooked directly into the mouth, pulling it permanently open. This did not work out as it made it impossible for the actor to speak. However, Peter Jackson liked the idea of the robe flowing up into the helmet and this was retained for the final version.
In another departure from the text, Aragorn refuses to believe the emissary's insinuation that Sauron has recovered the Ring, and decapitates him with Andúril; whereas in the book, the Mouth of Sauron claims diplomatic immunity, saying "I am a herald and ambassador and may not be assailed!" Gandalf observes pointedly that he has not been threatened.
Jackson said that he had cut the encounter from the theatrical version due to its lack of effect; he commented that in the book it was dramatic since the reader does not know Frodo Baggins' fate, but in the film the audience knows that both Frodo and Samwise Gamgee are alive. Once the Mouth is beheaded, his horse and body are not visible in the following shot as Sauron's armies of Orcs march through the Black Gate, even though Aragorn's sword is visibly stained with his blood.
He is also featured in EA Games' The Lord of the Rings: The Return of the King video game, and Warner Brothers' The Lord of the Rings: Aragorn's Quest as a boss character the player must defeat, in both games he appears in the level 'The Black Gate'. He is also a playable villain in The Lord of the Rings: The Battle for Middle-earth II, The Lord of the Rings: The Third Age (GBA) and The Lord of the Rings: Conquest.
