Jigsaw

When a newspaper columnist is murdered while investigating the Crusaders, a flag-waving hate group building itself into a political power, assistant district attorney Howard Malloy (Franchot Tone) is named special prosecutor and digs into the shadowy organization. The film is famous for its uncredited cameos — Marlene Dietrich, Henry Fonda, John Garfield, Burgess Meredith, and Everett Sloane all turn up in small roles as a favor to director Fletcher Markle. Produced by the Danziger brothers and released by United Artists, Jigsaw is in the public domain.
