Speaking of bounty hunters, it takes a really unsavory character chasing after outlaws to make the audience sympathize with the gang instead of the law. Marlon Brando was just such a character as a regulator who hunts down Tom Logan’s (Jack Nicholson) jolly band of rustlers.
The Missouri Breaks matches the freedom vs order theme of the dying frontier that Red Dead Redemption 2 seems to be going for. Nicholson’s character is a semi-decent guy who just happens to be stealing horses from a land baron that has enough money to have him and his friends all killed. Plus, you can’t help but notice that he even looks a bit like both RDR protagonists. If the young John Marston had his own gang, this is how I’d picture it.
