For a while, this first Hammer sci-fi offering is actually quite interesting: two childhood friends develop a machine that can replicate anything - animal, vegetable, mineral - you name it. When "Robin" (John van Eyssen) marries their childhood friend "Lena" (Barbara Peyton) his co-developer, "Bill" (Stephen Murray) contrives to makes an identical version of his own whom he calls "Helen". Now the fly in his ointment is that "Helen" is too good a duplicate - unfortunately she loves his mate too - and so poor old "Bill" is faced with a real dilemma. The story is quite fun, but the acting is prett...
