Concept art and test shots from Willis O’Brien’s War Eagles, a film that would have followed up O’Brien’s triumph, King Kong. The script was by Cyril Hume, who wrote all the MGM Tarzan films and Forbidden Planet. The plot is that explorers find a lost valley filled with a lost tribe of Vikings who ride giant eagles. In the finale, the Nazis would attack New York with a zeppelin fleet and attackw with something like an early EMP, only to be defeated by our hero with an army of giant eagles.
Of all of the great unmade movies, I wish this one had been made most of all.
