Directed by Brennon Jones and Paul Wynne, Alien 51 revolves around a genetic-engineering experiment gone haywire, as projects involving dangerous alien DNA are wont to do. This time, the fanged, half-alien creature escapes from the confines of the lab and ends up terrorizing a circus that had initially planned to make him a sideshow attraction. The film stars Mia Riverton and Heidi Fleiss. ~ Tracie Cooper, All Movie Guide
