The Conqueror(1956) Page

The Conqueror (1956) is infamous as a critical failure due to John Wayne's casting as Genghis Khan and is linked to a deadly, high-cancer rate among cast and crew due to filming in a Utah area contaminated by nuclear fallout. The production's association with cancer prompted Howard Hughes to buy all copies, hiding the film for nearly 20 years. Read a full account of the production's history at hometownstohollywood.com .
