Vincent Price is missing from this, the third and final installment of the series. By this time this was produced, Price was under contract to American International Pictures.
This film was rarely seen for many years, as it was the only entry in the entire Fly film franchise never to receive a videotape or laserdisc release. It did not receive its home video premiere until 2007, when it was released on DVD in a box set with the original series of films.
