I... Comme Icare (aka I As In Incarus) (1979)

Set in an unnamed country in the West. After the assassination of a President (Gabriel Cattand), an investigation committee comes up with questionable conclusions about a lone gunman. One of the commission's members, the state attorney (Yves Montand) disagrees with the conclusions of his peers. He reopens the case and unspools a tightly wound conspiracy plot. Directed by Henri Verneuil (THE SICILIAN CLAN), this is a zealous conspiracy thriller that takes a methodical approach to its subject rather than the intense pacing of a conspiracy thriller like Costa Gavras' Z. This does not mean it's any less exciting (though it never reaches the potent power of Z) but its leisurely pace diffuses some of the movie's potential intensity. Although a product of France, the location of its fictional narrative is never mentioned but the film is obviously inspired by the Kennedy assassination and the Warren Commission Report. The film received five Cesar (the French Oscar) nominations including best picture. With Michel Albertini, Henry Djanik, Jean Lescot, Jean Negroni and Francoise Bette.
