Big Kill

When Johnny Kane first meets Jake in the bar he says to Jake: "I hear you're real fast" to which Jake responds: "I'm just a sporting man." This is the same thing Johnny Ringo says to Doc Holiday in the film Tombstone and Doc gives a similar response. A very obvious homage the now classic western.

Everybody in Big Kill denies knowing anybody named Grant when Jim asks around, but he is the mayor of the town. And nobody is surprised when Jim calls him Grant, so it is not as if Grant has been living there incognito or under a different name. This is never explained in the movie.

Perhaps they were protecting the head of the illegal rustled cattle crew that provides much of the town's revenue.
