Slim Pickens was cast in Dr. Strangelove somewhat last-minute. Originally, Peter Sellers had been slated to play the bomber pilot, along with his three other roles, but a knee injury required him to bow out of the fourth role.
Pickens had been in One-Eyed Jacks a few years before. That movie had originally had Stanley Kubrick in the director’s chair, but Kubrick had clashed with its star, Marlon Brando, who went on to direct it himself.
Had Pickens already joined the One-Eyed Jacks cast when Kubrick was still directing it? Had they worked together, albeit briefly, before Pickens joined Dr. Strangelove?
