This episode had a very interesting cast. Rafael Campos is listed as a co-star on the same screen as Steve McQueen. At the end of the episode, he declares that he is Pancho Villa, which was a big deal back in the 1950s. Several Pancho Villa movies were made in the 1950s-1960s era. In Have Gun, Will Travel; Rafael Campos appears again in an episode called "Pancho" from 1959. Once again, at the end of the episode he declares that he is Pancho Villa.
Bing Russell (father of Kurt Russell), Miriam Colon (playing the wife of Carlos Romero), and Tom Gilson are also in this episode. Tom Gilson's fifteen minutes of fame happened in 1962 when his wife shot him to death with a 12-gauge shotgun. He also gets killed in this episode. He usually played a second-string thug or villain, and he usually got killed in every role he played.
The story is that Randall (McQueen) is trying to bring in Carlos Romero from Mexico for the bounty in the U. S. Rafael Campos shoots Randall and is constantly harassing him during this episode, because Romero is his uncle, and he does not believe he can get a fair trial in the USA. Bing Russell and Tom Gilson are two other bounty hunters who also want to kill Randall so they can steal Romero and his bounty.
As often happens in Westerns, all hell breaks loose on poor Josh Randall! This episode was action-packed. The worst part was Rafael Campos over-acting his Pancho Villa. I wonder if there was a Pancho Villa TV series planned that never happened? It would explain why Randall did not kill him off, even after Pancho shot Randall.
