Responsible for kidnapping his latest client's daughter, the head of a private detective agency hires his least competent employee to work this case, only to be baffled when the man's incompetence helps him make headway in this lively comedy starring John Candy. Donning several different disguises (thanks to some stellar makeup work) as he goes about solving the case, Candy's performance has brought about comparisons to Chevy Chase in 'Fletch', however, with Candy's utter incompetence, this is actually a very different sort of film. Candy is thoroughly likable throughout with his heart (if not his mind) always in the right place and there is a lot to like in how he benevolently takes the victim's neglected teenage sister under his wing without any trite romantic sparks igniting between them. Above all else though, 'Who's Harry Crumb?' is a laugh-out-loud affair with such zaniness as a footsies scene in which three characters at a table each think that someone else is playing with them. A large number of gags are admittedly foreshadowed too heavily in advance for full effect, such as Candy landing in a sitting position in a living room sofa and Candy crashing into a glass cabinet, however, they are still funny thanks to Candy's near nonchalance towards his buffoonery, carrying on in almost all cases as if nothing has even happened. Indeed, while some have dismissed the movie due to the slapstick nature of most of the gags, it is how Candy handles himself in these moments rather than the physical humour itself which generates the most laughs.
