With his mother fresh in her grave after losing her sanity, the young Philippe Delambre resumes his father's research in an attempt to succeed where his father had failed in the transmission of living matter through time and space. Tragedy strikes twice, however, as Philippe suffers the same damnable fate as his father in becoming a half-human freak! RETURN OF THE FLY follows many of the same familiar steps as the original, but lacks the emotional strength shared between the two leads from before. The great Vincent Price plays a much larger role in this second film, serving as a friend and mentor to his stubborn nephew. What is most unique in this feature is Philippe's growing paranoia of the pesky flies that seem to trail his every move, a bit of foreshadowing that leads towards an all-too-expected end. A subplot involving industrial espionage also adds a touch of Film Noir to the scientific backdrop. Philippe's monstrous alter-ego does not make an appearance until late in the picture, but while the creature's design is quite impressive, its bulbous head does seem rather silly. RETURN's greatest casualties then becomes its conflicting plot tools, sluggish pace, and surprisingly upbeat ending, which hold it back from becoming more successful. Still, RETURN OF THE FLY provides ample shocks in its final scenes to please the fans that eagerly awaited a sequel.
