Jungle Devil

"Daily Planet" reporters Clark (George Reeves), Lois (Noel Neill) and Jimmy (Jack Larson) head into a treacherous jungle, searching for a scientific expedition which has vanished. The local natives prove quite hostile to the "intruders" because the jeweled eye of a native idol has apparently been stolen. This is the episode in which Clark's alter ego Superman not only wrestles a gorilla, but also uses his bare hands to convert a lump of coal into a diamond!
