A TV movie made for and broadcast on the CBS network, although the original series the movie is based on ran on NBC, which later merged (after this film was made) with the production company, Universal, to become NBCUniversal.
Former U.S. Marshal Sam McCloud (Dennis Weaver) is the newly elected Junior Senator from New Mexico, but it is never mentioned whether he was elected as a Democrat or a Republican, except, if you look very closely, when his niece (Melissa Sue Anderson) falls on the roadway in the opening scene, a newspaper clipping falls out of her case, and the headline reads: "Marshal Sam McCloud Victorious as the New Rep. Senator for New Mexico," "Rep." meaning he was elected as a Republican.
Although it was listed on screen in the opening credits of this TV movie, as "Created by Herman Miller," the Writer's Guild of America (WGA) did not submit Miller's name along with screenwriter Michael Sloan for credit to IMDb, even though Miller is listed as the creator on every original episode of Ein Sheriff in New York (1970), and wrote both the story and screenplay for the movie Ein Sheriff in New York (1970) is based on, Coogans großer Bluff (1968).
