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, writes Snopes, "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.
