Burt Reynolds or Franco Nero
I was very impressed by Burt Reynolds performance and felt the film would have suffered it if starred Corbucci's usual leading man, Franco Nero. I'm beginning to think Burt Reynolds would have been great as Django. He really could of been a rival to Clint Eastwood if he had kept working with Corbucci.
I understand that Burt Reynolds didn't get along with Corbucci and has called Navajo Joe the worst experience of his life.
