The Man Called X
Herbert Marshall had the lead role of agent Ken Thurston/"Mr. X" who took on dangerous cases in a variety of exotic locations. Leon Belasco played Mr. X's comedic sidekick, Pegon Zellschmidt, who always turned up in remote parts of the world because he had a "cousin" there. Pegon would annoy and help Mr. X. Wendell Niles was the announcer from 1947 to 1948. Gordon Jenkins Orchestra supplied the background music.
