My review was written in November 1989 after watching the film on Prism video cassette.
"Alienator" is a tongue-in-cheek sci-fi thriller geared toward home video fans with a soft spot for the old stars and old-fashioned serials.
Film dovetails closely with previous pics by Fred Olen Ray, particularly "Star Slammer", in a tale of rebel leader Ross Hagen, who escapes execution on a remote prison planet and travels to Earth. Muscle lady Teagan Clive (as the title "Alienator" character) is sent to destroy him and his Earthling youngsters, Jesse Dabson and Dawn Wildsmith, who have befriended Hagen.
The appearance of genre vets like Robert Clarke and Robert Quarry is a plus, but "Alienator" suffers from a weak script. Leads Jan-Michael Vincent and John Phillip Law have little to do; Wildsmith is cast against type in an uncharacteristically wimpy role, and P. J. Soles is stuck in a rather goofy costume as an outer space technician.
Not enough is made of Teagan Clive, the Alienator. She's strange and awesome looking in a revealing heavy metal outfit but had a much better role in the Italian horror film "Obsesion: A Taste for Fear".
Tech credits are adequate.
