Johnny stars as a character named Johnny Weissmuller rather than Jungle Jim in the first of three such pictures made after the last of the Jungle Jim movies, are well-nigh indistinguishable save for new names for the protagonist and the chimp. This time around, Johnny investigates reports of thefts of cobalt from a uomine operated by John King (Steve Darrell) and his ward, Luora (Judy Walsh), involving attacks by men disguised as crocodiles. Suspicion falls on King’s brother Arnold (David Bruce), but more is going on than is immediately apparent. Overall, a rather tired affair.

  Not recommended, save for completists. Otto thinks you should avoid this movie.

Movie 431 for 2021.
