Mirage (1965)

From an article, Film noir goes to war, in the TLS by Philip French:

Edward Dmytryk, Canadian son of Ukrainian immigrants, worked his way up in the cinema business from studio messenger boy to make Farewell My Lovely [aka Murder, My Sweet (1944)] . He followed this with two other crucial noir pictures, Cornered (1945), about war crimes and neo-Nazism, and Crossfire (1947), centring on returning veterans and post-war anti-Semitism. He was one of the Hollywood Ten, left-wing filmmakers jailed for refusing to cooperate with the House Un-American Activities Committee (HUAC). Unlike the others, he emerged from prison to reappear before HUAC, name former Communist associates and go back to work, making large-scale anti-Communist and conformist potboilers. But in 1965 he directed Mirage, an undervalued noir thriller, shot in black-and-white, turning on one of the genre’s favourite themes, amnesia, and indicting the military-industrial establishment which Dwight D. Eisenhower had warned against in one of his final speeches as President. It helped open the way for a new kind of political cinema that was to include such post-Watergate movies as The Parallax View and Three Days of the Condor.
