Khartoum was a champion racehorse owned by movie producer Jack Woltz.
The Triple-Crown winner was bought for $600,000 by Woltz and who put his horse out to "stud". The horse had a fine stable built for him, the best vets and horse breeders that money could buy, and even a small team of private detectives to guard him 'round the clock. Woltz was very attatched to the horse, his pride and affection for the animal clearly evident. Khartoum was eventually killed and decapitated and then put in Woltz's bed by Luca Brasi to convince Woltz to grant Johnny Fontane the lead in the new war movie he was shooting. Upon discovering Khartoum's severed head Woltz swore his staff to secrecy and had Khartoum quietly buried and his stables all torn down.
- Khartoum is a reference to Charles Gordon, the British commander of Khartoum in the Sudan in 1885, who was captured by Sudanese Muslims and was ironically also beheaded.
- For the horse's head, director Francis Ford Coppola requisitioned a real head from a dog food company, and had it's head painted from white to brown, to match up to the horse seen earlier.
