Jack Cunningham was an American scriptwriter who started out during the silent era. Cunningham provided continuity for such Douglas Fairbanks epics as The Black Pirate (1925), Don Q, Son of Zorro (1925) and The Iron Mask (1929). He also tied up a few loose plot ends in the location-filmed 1928 effort White Shadows in the South Seas. Working at Paramount in the 1930s, Cunningham did touch-up work and/or full screen treatments for W.C. Fields' Mississippi (1935) and Man on the Flying Trapeze (1935), Harold Lloyd's Professor Beware (1938) and C. B. DeMille's Union Pacific (1939), to name but a few. He was promoted to producer of the 1936 Paramount programmer Easy to Take. Though Cunningham did take on a couple of acting roles late in his career, he should not be confused with the British actor of the same name, who appeared onscreen in the '50s and '60s.
