"'Fraidy Cat" is a Columia Pictures remake of a previous comedy, the Three Stooges film, "Dizzy Detectives". The studio very often remade prior films the studio made...and having some other act remake a Three Stooges picture isn't unusual. What would have been unusual is if the remake had been better...which, unfortunately, it isn't.
Joe and Jim Hawthorne both play dippy detectives who are working a case involving a gorilla...or, rather, some guy dressed in a cheesy gorilla costume. Already the film loses a point or two for the gorilla! During the course of the two idiots' investigation, Joe appears to have his head cut off and Jim sees it and the pair later find that crooks are using the poor gorilla to steal!
The film frankly isn't any improvement on the Stooges movie. It even replicates a LOT of scenes...though having Curly, Moe and Larry instead of Besser and Hawthorne is a major plus. Watchable.
