The greatest misnomer ever in human history, as Alex Gibney’s disturbing new Gitmo documentary proves, is using the word “intelligence” in the name of the Central Intelligence Agency.

In The Forever Prisoner, Gibney chronicles the torture and imprisonment of Saudi Arabian Abu Zubaydah, who, after almost twenty years of imprisonment, has never been charged with a crime — one of only twenty-nine prisoners still behind bars at the Guantanamo Bay detention camp. The troubling film specifically probes the roles played by psychologists — as well as high-ranking government officials in both the CIA and the Justice Department — in Zubaydah’s enhanced interrogation.

A prolific producer and director, Alex Gibney has long specialized in making nonfiction films about corrupt elites’ abuses of power and human rights. The targets Gibney has fearlessly tackled in his prodigious oeuvre include, among many others, a war criminal in The Trials of Henry Kissinger; überlobbyist Jack Abramoff and GOP majority whip Tom “The Hammer” DeLay in Casino Jack and the United States of Money; clerical abuse in Mea Maxima Culpa: Silence in the House of God; and Big Pharma in The Crime of the Century.
