is a 1958 British biographical historical drama film based on the Dreyfus affair, in which a Jewish captain in the French Army was falsely accused of treason and imprisoned for five years before being pardoned.

He is sentenced to life imprisonment on Devil's Island while the real spy, Major Ferdinand Walsin Esterhazy, helps in the investigation.

Émile Zola writes an open letter to the prime minister of France entitled I Accuse!, which reveals the truth behind the cover up.

"[8] The Philadelphia Inquirer was unimpressed: "For no immediately apparent reason, the Dreyfus scandal...is being given a new screen airing....more zeal than art....Gore Vidal's plodding writing is almost constantly at odds with the overly melodramatic or numbed performances director-star Ferrer has elicited from himself and his cast....If Ferrer underplays drastically, the reverse must be said for almost everyone else in the large, hard-pressed cast.

"[9] New York Times critic Bosley Crowther wrote that the film's "studious and generally valid re-enactment of the highlights of the case offers rewards," but said the film lacked excitement and drama and that "Mr. Ferrer's Dreyfus is a sad sack, a silent and colorless man who takes his unjust conviction with but one outburst of protest and then endures his Devil's Island torment lying down.
