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 pretty mediocre and the dialogue a bit too staccato to keep the story flowing. The effects, such as they are, are a bit on the basic side too with sets that wobble and glow like an old edition of "Dr. Who". It's not terrible, and as a first effort in his genre from a studio far better versed in horror genres, is an ok watch from writer/director Terence Fisher.
