This is a Roland Winters' Monogram made Chan flick. It is a remake of their earlier "Mr. Wong, Detective". Neither version is very exciting. Winters is a very weak Chan, at best. Only Victor Sen Young and Mantan Moreland brighten the film. This is one of the films that has Young playing "No. 2 Son Tommy"! He used to be "No. 2 Son Jimmy". Tommy was Benson Fong and No. 3 Son. It is sort of an ongoing blooper in the later Monograms.
