In the Year of the Pig is an American documentary film directed by Emile de Antonio about American involvement in the Vietnam War. It was released in 1968 while the US was in the middle of its military engagement, and was politically controversial. In 1969, the film was nominated for the Academy Award for Best Documentary Feature. In 1990, Jonathan Rosenbaum characterized the film as "the first and best of the major documentaries about Vietnam".
The film, which is in black and white, contains much historical footage and many interviews. Those interviewed include Harry Ashmore, Daniel Berrigan, Philippe Devillers, David Halberstam, Roger Hilsman, Jean Lacouture, Kenneth P. Landon, Thruston B. Morton, Paul Mus, Charlton Osburn, Harrison Salisbury, Ilya Todd, John Toller, David K. Tuck, David Wurfel and John White.
Produced during the Vietnam War, the film was greeted with hostility by many audiences, with bomb threats and vandalism directed at theaters that showed it.
De Antonio cites the film as his personal favorite. It features the ironic use of patriotic music, portrays Ho Chi Minh as a patriot to the Vietnamese people, and asserts that Vietnam was always a single country rather than two.
