Question: Who was known for playing a fictionalized version of the wild politician who was the face of communist scare tact's in the early 1950's?

Context:
The Year of Living Dangerously (novel)
The Year of Living Dangerously is a 1978 novel by Christopher Koch in which a male Australian journalist, a female British diplomat, and a Chinese-Australian male dwarf interact in Indonesia in the summer and autumn of 1965.
 Set primarily in the Indonesian capital city of Jakarta, it also describes a partly fictionalized version of the events leading up to the coup attempt by the Communist Party of Indonesia on September 30, 1965.
Red-baiting
Red-baiting, also reductio ad Stalinum, is an informal logical fallacy that intends to discredit the validity of an opponent's logical argument by accusing, denouncing, attacking or persecuting an individual or group as communist, socialist, or anarchist, or sympathetic toward communism, socialism, or anarchism.
 In the United States the term "red-baiting" dates from at least 1927.
 In 1928, black-listing by the Daughters of the American Revolution was characterized as a "red-baiting relic".
 It is a term commonly used in the United States, and in United States history, red-baiting is most often associated with McCarthyism, which originated in the two historic Red Scare periods of the 1920s (First Red Scare) and 1950s (Second Red Scare).
 In the 21st century, red-baiting does not have quite the same effect it previously did due to the fall of Soviet-style Communism, but some pundits have argued that notable events in current American politics indicate a resurgence of red-baiting consistent with the 1950s.
Charles de Batz de Castelmore d'Artagnan
Charles Ogier de Batz de Castelmore, Comte d'Artagnan (] ) ( 1611 – 25 June 1673) served Louis XIV as captain of the Musketeers of the Guard and died at the Siege of Maastricht in the Franco-Dutch War.
 A fictionalized account of his life by Gatien de Courtilz de Sandras formed the basis for the d'Artagnan Romances of Alexandre Dumas, most famously including "The Three Musketeers" (1844).
 The heavily fictionalized version of d'Artagnan featured in Dumas' works and their subsequent screen adaptations is now far more widely known than the real historical figure.
Joseph McCarthy
Joseph Raymond McCarthy (November 14, 1908 – May 2, 1957) was an American politician who served as U.S. Senator from the state of Wisconsin from 1947 until his death in 1957.
 Beginning in 1950, McCarthy became the most visible public face of a period in the United States in which Cold War tensions fueled fears of widespread Communist subversion.
 He is known for alleging that numerous Communists and Soviet spies and sympathizers had infiltrated the United States federal government, universities, film industry, and elsewhere.
 Ultimately, the smear tactics he used led him to be censured by the U.S. Senate.
 The term "McCarthyism", coined in 1950 in reference to McCarthy's practices, was soon applied to similar anti-communist activities.
 Today, the term is used in reference to what are considered demagogic, reckless, and unsubstantiated accusations, as well as public attacks on the character or patriotism of political opponents.
Lavender scare
The lavender scare refers to a witch hunt and the mass firings of gay people in the 1950s from the United States government.
 It paralleled the anti-communist campaign known as McCarthyism and the Second Red Scare.
 Gay men and lesbians were said to be security risks and communist sympathizers, which led to the call to remove them from state employment.
