I recall reading that John Wayne was filming a movie near a Nevada underground test and got terminal cancer as a direct result. Don't know if that's true.
John Wayne got terminal lung cancer because he smoked three packs of cigarettes a day.
The movie in John Wayne question was the 1956 production of “The Conqueror” John Wayne as Ghengis Kahn and Susan Hayward as the Princess Botai.
It’s Hollywood folks what can I say :-)
IMDB listing of the move here... http://www.imdb.com/title/tt0049092/?ref_=nv_sr_1
An interesting post from IMDB regarding the supposed “cancer cluster” from the filming of the movie...http://www.imdb.com/title/tt0049092/board/nest/193872130?ref_=tt_bd_2
John Wayne passed on June 11, 1979 23 years or so after the movie was filmed FWIW
Y’all have a great weekend I is off to work in a bit
