Kamarag In the late 23rd century , the Klingon ambassador Kamarag was the official representative of the Klingon Empire in the Federation . He was a hotheaded , but effective , diplomat who spoke with dramatic hyperbole . He made no secret of his dislike for James T . Kirk and had a personal dislike for Sarek . Service record . In early 2286 , Kamarag loudly protested the Federation ' s development of the previously classified Project Genesis , which he claimed was central to a plot aimed at annihilating the Klingon species . His claims were debunked by Sarek , as he pointed out that Genesis was named for creation of life and accused the Klingons of committing murder in their attempt to learn its secrets . Kamarag defended their actions , proudly stating that they had a right to preserve their race . When Sarek tried to speak on behalf of Kirk , Kamarag accused Sarek of harboring a personal bias , as Kirk had rescued Sarek ' s son , Spock . When the Federation Council refused to prosecute Admiral Kirk for supposed war crime s against the Klingons in defending the from a Klingon attack on the , Kamarag proclaimed that there would be no peace as long as Kirk lived . He then angrily left , with a couple of Klingon aides , as someone in the Council referred to him as a " pompous ass . " ( ) In 2293 , Kamarag defended his government ' s reasons for arrest ing Kirk and Leonard McCoy and charging them with the assassination of Gorkon , the chancellor of the Klingon High Council , under the rules of interstellar law . Kamarag was also present at the Khitomer Conference , where the first peace treaty between the Federation and the Empire was signed , begrudgingly applauding Kirk ' s efforts in preventing the assassination of the Federation President and the new Klingon Chancellor , Azetbur . ( ) Appendices . Background information . According to " " ( # 111 , p . 40 and # 138 , p . 30 ) , Eddie Murphy was at one point expected to portray the Klingon ambassador in " Star Trek IV " , although John Schuck – who wound up portraying the character – had no idea about this situation until after his own involvement in the film ' s production . Schuck recalled how he first learned of the role , noting , " " I was interested in reading for the part in " Star Trek IV " . " " ( ) Somewhat due to his ex - wife Susan Bay , who later married Leonard Nimoy , John Schuck was called in to read for the role of the Klingon ambassador , after Nimoy agreed to see him and take the interview . " " The first thing he said when I walked into the office , " " recalled Schuck , " " was , ' I don ' t think this is going to work . " " This statement , of course , did not set Schuck at ease for the rest of the interview . ( ' , issue # 138 , pp . 28 - 29 ) He nevertheless read a scene for Nimoy . " " He said , ' Thank you John , that was very good but we can ' t use you . " " ( ) When Schuck asked Nimoy why not , Nimoy professed that he thought Schuck was too young for the part . ( ' , issue # 138 , p . 29 ) John Schuck noticed that , on Leonard Nimoy ' s desk , there was a drawing of the ambassador , clad in his Klingon robes . ( ) As Nimoy informed Schuck , the illustration had been drawn by Costume Designer Bob Fletcher . " " Bob had shown an awful lot of facial hair ; the Ambassador had a beard that was white with grey , " " remembered Schuck . ( ' , issue # 138 , p . 29 ) His immediate reaction was to exclaim to Nimoy that a six - or ten - year old boy could get dressed in the costume and thereby look the right age . ( ' , issue # 138 , p . 29 ; ) After reminding Leonard Nimoy that he would very much like to try the role , John Schuck ' s audition continued . " " I ended up reading – and I ended up getting the part , " " he related . " " Now that was very , very nice . " " The Klingon ambassador ' s costume was fitted at Western Costume . This procedure involved many people , because boots had to be specifically made for John Schuck to play the role . Also designed and fitted especially for the scenes including the ambassador , which were to be shot over two days , were gloves and an extraordinary amount of jewelry . " " It was very exciting to be attended to in that way , and be able to give input into the character , " " stated Schuck . However , he was very concerned – since mistakes had repeatedly happened – that the cape be of a lightweight design , later commenting , " " The cape had to be weighted properly , so that it didn ' t pull me backwards and , at the same time , without knowing what the blocking was , if I had a quick movement I didn ' t want to find 10 yards of material under my feet to fall over . " " ( " " , issue # 138 , p . 29 ) The makeup for the Klingon ambassador also had to be created and undergo some subtle fine - tuning . " " Putting it on for the first time , seeing what areas were weak , how it worked involved a good half - day , " " John Schuck remembered . Putting his skin at risk , Schuck insisted on maintaining the color consistency between the prosthetic pieces and his skin . " " I said that I was only going to be there for two days , so use the same [ base ] on my face as the latex . They warned me about it , and indeed by the end of the second day , I had very little of my original skin left , but I felt that it contributed strongly to the look . " " In contrast , Schuck also remarked with a big grin , " I " didn ' t feel I looked that different in the makeup . I said , ' Four - and - a - half hours and look , no difference . " " George Takei approved of the look , describing it as " " a fantastic , elegant set of costumes for the Ambassador , and one of the most effective things about the costume is this full - flowing cape . [ . . . ] [ Shuck ] wears this cape well . He knows how to move in costumes that have the grandness , the sense of sweep . " " He further explained , " " I saw that cape and I said , " That cape belongs on Sulu . " I told Bob Fletcher the cape is something that can only be described as " Suluesque . " I wouldn ' t be a bit surprised if we see Sulu wearing that " Suluesque " Klingon cape in Star Trek V , VI or VII . I ' ve got my eyes on it . " " ( " " # 109 , , p . 18 ) Despite the Klingon ambassador being a relatively small role in " Star Trek IV " , John Schuck gave a notably strong performance in the part . He related , " " I had seen Christopher Lloyd do nothing but talk Klingonese and I realized I didn ' t have to do that . I needed to make the Ambassador as Human a character as possible . I didn ' t think of him as a bad person , but someone with a point of view , a person of accomplishment . In my actor ' s mind , I thought of King Lear , so I made him quite theatrical . " " ( ) Schuck also stated , " " My image was of a man of the stature of King Lear or any of the Shakespearean greats , a man of passion and conviction , so that what we did not have in this scene was a man who was just crying out in the world merely because Klingons are mad , angry people . I wanted to have someone of passion , who was convinced that his people were justly wronged . I felt that was a very positive attitude to have [ . . . ] I used a very vocal approach to the Ambassador , and felt that I did do him as a very stentorian orator , extremely skilled and shrewd in how he chose his words , and he loved doing it . There was that sense of being on stage about the character . I don ' t know whether I took the scene – I wasn ' t trying to – but I certainly felt that I commanded attention as someone of stature , and that was primarily all I wanted to do for that small amount of time . And Leonard went along with all that . As a director , he was very , very supportive . " " Even though the scene featuring the ambassador required only two days to film , Schuck remained pleased to have the role . ( " " , issue # 138 , pp . 29 & 30 ) Gene Roddenberry approved of John Schuck ' s take on the Klingon ambassador in " Star Trek IV " , the actor subsequently reporting , " " [ He ] loved the humanness I brought to the character . " " Aside from interviews , Schuck had absolutely no public recognition , by , for portraying the Klingon Ambassador in the movie , owing to the elaborateness of the character ' s Klingon makeup . " " I ' ve heard people say that they realized it was me only when they recognized the voice , " " relayed Schuck . Many viewers of the movie expected the ambassador to return at the end of the film , as did Schuck himself . ( " " , issue # 138 , p . 30 ) In the reference book " " ( pp . 150 & 151 ) , this character is named " Kamarag " . The same book ( p . 151 ) states that , in 2289 , he was approached by the same Federation president who appears in " Star Trek IV " , as the president was interested in seeking one final chance at negotiations between the two powers , and that Kamarag consequently consulted his government , which agreed to welcome a Federation delegation on Korvat colony , beginning peace talks ( as mentioned in ) which proceeded the Khitomer Conference . Apocrypha . The novelizations of the Klingon Ambassador ' s movie appearances , written by J . M . Dillard , also refer to the character as " Kamarag " .
