About this listen

 Before there was James Bond, I Spy, or Danger Man, there was The Man Called X.

The Man Called X began during the latter part of World War II as the founding of the O.S.S. sparked public interest in espionage, spies, and secret missions. The series outlasted the war and starred Herbert Marshall as the Man Called X (aka Ken Thurston) traveling the world to troubleshoot threats to peace, the security of the U.S., and the world into the 1950s.

In his journeys, Thurston was joined by a criminal and conman Pegon Zellschmidt (Hans Conreid and then Leon Belasco) who would assist Thurston but also often would sell him out to the bad guys before eventually helping him in the end.

The series began as a summer replacement in 1944 over CBS and was picked up for 26 26-week run over the Blue Network (which later became ABC) in the fall of 1944. It was then brought back for summer runs over NBC in 1945 and 46, before landing back at CBS for a seventy-eight week run from 1947-48. After two years off the air, the series returned to NBC for its final two seasons where it aired along with the similar Dangerous Assignment. The concept was revived as a syndicated TV show starring Barry Sullivan in 1956.
