Slim Pickens, an established character actor and veteran of many Western films, was eventually chosen to replace Sellers as Major Kong after Sellers' injury. Terry Southern's biographer, Lee Hill, said the part was originally written with John Wayne in mind, and that Wayne was offered the role after Sellers was injured, but he immediately turned it down. Dan Blocker of the "Bonanza" western television series was approached to play the part, but according to Southern, Blocker's agent rejected the script as being "too pinko". Kubrick then recruited Pickens, whom he knew from his brief involvement in a Marlon Brando western film project that was eventually filmed as "One-Eyed Jacks".
