The Manchurian Candidate is a 1962 American black and white suspense thriller film about the Cold War and sleeper agents. It was directed and produced by John Frankenheimer. The screenplay was written by George Axelrod, and was based on the 1959 Richard Condon novel The Manchurian Candidate. The film's leading actors are Frank Sinatra, Laurence Harvey and Janet Leigh, with Angela Lansbury, Henry Silva, and James Gregory among the performers cast in the supporting roles.[4]
Noirish, it is set in a somewhat different social setting to the film noirs of the late 1940s.[4] The plot centers on the Korean War veteran Raymond Shaw, the progeny of a prominent political family. Shaw was a prisoner of war during the conflict in Korea and while being held was brainwashed by his captors. After his discharge back into civilian life, he becomes an unwitting assassin involved in an international communist conspiracy. Officials from China and the Soviet Union employ Shaw as a sleeper agent in an attempt to subvert and take over the United States government.
The film was released in the United States on October 24, 1962, at the height of U.S.-Soviet hostility during the Cuban Missile Crisis. It was well-received by critics and was nominated for two Academy Awards: Best Supporting Actress (Lansbury) and Best Editing. It was selected in 1994 for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant."

Gene Hackman,
The Conversation:

The Conversation is a 1974 American mystery thriller film written, produced and directed by Francis Ford Coppola and starring Gene Hackman with supporting roles by John Cazale, Allen Garfield, Cindy Williams, Frederic Forrest, Harrison Ford, Teri Garr and Robert Duvall.
The plot revolves around a surveillance expert and the moral dilemma he faces when his recordings reveal a potential murder. Coppola cited the 1966 film Blowup as a key influence. However, since the film was released to theaters just a few months before Richard Nixon resigned as President, he felt that audiences interpreted the film to be a reaction to the Watergate scandal.
The Conversation won the Grand Prix du Festival International du Film, the highest honor at the 1974 Cannes Film Festival. It was nominated for three Academy Awards in 1974 and lost Best Picture to The Godfather Part II, another Francis Ford Coppola film. In 1995, it was selected for preservation in the National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
The Gene Hackman character was based on a local investigator, Hal Lipset:
