Jules Dassin—the blacklisted director of such suspense classics as Brute Force (1947), Thieves’ Highway (1949), and Rififi (1955)—collaborated with actress Ruby Dee on the screenplay of this 1968 drama, which transposes the story of Liam O’Flaherty’s Irish novel The Informer to a group of black revolutionaries in Cleveland. With Roscoe Lee Browne.
