Walter Brennan's part is a spoof of his part in My Darling Clementine, in which he is head of the Clanton clan.
The film's title is a parody of a bumper sticker popular around the time it was made, "Support Your Local Police" part of the "law-and-order" movement led by such politicians as Richard Nixon, Ronald Reagan and George Wallace.
Though not a sequel or related to the original story line, this movie was followed by Support Your Local Gunfighter with most of the cast intact playing similar characters.
