Slim Pickens rules!
And for trivia lovers, the character of Dr Strangelove was inspired by Herman Kahn, author of ‘On Thermonuclear War’:

Peter Sellers was supposed to also play Maj. Kong, but he fell out of the B-52 mockup, and broke a leg on the first day of filming as Maj. Kong. Kubrick, faced with financial catastrophe, if he had to wait weeks for Seller's leg to heal, before he resumed shooting, looked for someone who could walk onto the set and speak in the Texas accent that Sellers had struggled for months to master. Pickens, a Californian who had spent years on the rodeo circuit, got the job, and went immediately to work.
