Bill and Robin, helped by their childhood friend, Lena, develop a "reproducer" which can exactly duplicate any object. Bill, crushed when Lena marries Robin, convinces her to allow him to duplicate her, so that he may have a copy of her for himself. The experiment, at first deemed a success, seems to have worked only too well as the duplicate, Helen, is such an exact copy that she also loves Robin, not Bill. Bill hopes to rectify the situation with another radical experiment. Written by Doug Sederberg <vornoff@sonic.net>

A Real Body Double
17 April 2006 | by BaronBl00dSee all my reviews

Rather clever, perhaps over-drawn science fiction(for lack of another fitting category) about two young men who discover how to replicate any matter whatsoever. The two lads are assisted by gorgeous Barbara Payton and only one of the guys gets the girl. Soon the other pines for his lost love and tries sending live matter through the replicating devices with the express purpose of duplicating his lost love Lena. Hammer horror icon Terrance Fisher directs this early Hammer film with style albeit on a small scale with a very limited budget. The science of the film shouldn't be dwelled on too terribly long if you want to buy into the film, and it is the means to tell a story of a love triangle which soon has a fourth side - a four sided love triangle. The film has a lot of narration by James Hayter as a doctor that took in one of the men as a boy. Hayter adds some much needed credibility to the film and is a voice of reason - to a degree - and compassion. The implications of the new technology are only superficially explored and soon you see the plot turning into yet another Frankenstein -type film with man destined to try and become God and create life. What makes this film work is Fisher's low-key direction and simple yet sturdy performances by all concerned. Payton is very lovely as well. While certainly not in the ranks of great Hammer films or great Fisher films, Four Sided Triangle is thought-provoking, engaging, and predictable.
