Come Back Charleston Blue is an okay followup [from the novel The Heat’s On by Chester Himes] by producer Samuel Goldwyn Jr to his successful 1970 Cotton Comes to Harlem, again featuring Godfrey Cambridge and Raymond St Jacques as offbeat, comedic Harlem gumshoes.
Cambridge and St Jacques find themselves caught between fading black drug king and mobster Maxwell Glanville, and Peter De Anda, ostensibly a successful photographer out to rid Harlem of drugs, but in reality eyeing the area for himself.
De Anda creates the impression that a series of gangland deaths has been caused by the ghost of Charleston Blue, a Depression-era hood, long dead.
The film lacks punch. The gags just don’t quite add up to solid laughs or excitement.
