By 1980 the grim tally attached to The Conqueror had entered the public imagination: of roughly 220 cast and crew members who worked on the production, 91 (about 41%) had been diagnosed with cancer and 46 (about 21%) had died of it. Those figures — much higher than what some scientists expected for a group that size — prompted immediate finger-pointing at fallout from nearby tests. Notable victims included director Dick Powell (lymphoma; he became ill in 1962 and died in January 1963), lead actor John Wayne (diagnosed with lung cancer in 1964, later died of stomach cancer in 1979), Susan Hayward (lung tumor that metastasized; died 1975), Pedro Armendáriz (who suffered earlier on-set injuries and later committed suicide in June 1963 after a terminal cancer diagnosis), and Agnes Moorehead (a non‑smoker and health fanatic who nevertheless died of cancer in April 1974). The tragedyladen roll call stoked speculation — and grief — among survivors and relatives, some of whom seriously considered litigation against the government for failing to warn the public about fallout risks.
