You’re not watching an episode from the The Twilight Zone.
No, this clip is from the 1950s western TV series Trackdown.
Or, to be more precise, it comes from a 1958 episode called “The End of the World.”
The clips features Lawrence Dobkin playing the role of “Walter Trump,” a fraud who rides into town claiming, “that only he could prevent the end of the world by building a wall.”
The episode ends, in case you’re wondering, with the fear-mongering Trump getting placed under arrest.
Freedom and sanity are restored. Hurray.
