I remember really enjoying "Nightmare of Eden" the first time I saw it, but you can’t help but see where in certain sequences the production of Nightmare of Eden could have been a lot better. The first thing that stands out are the spaceship model shot sequences which were shot on video over the course of two hours in a single day, but should have been shot on film, which would have taken four days. If they had shot it on Film like it normally was it would have looked a lot better. Problem number two would have to be Nightmare of Eden's monsters, the Mandrels. They're supposed to be terrifying and yet they look (as others have pointed out in the past!) like cute rejects from The Muppet Show. They look good in the Jungle where you can only see the shape of a Mandrel and its glowing eyes, but as soon as you move them to the ship where everything is flood lit, the Mandrels loose any scariness they might have had and end up just coming across as a bit of a laugh! On a better note however, one of the better effects of the story was when one of the Mandrels broke back down into the drug substance that the creatures were made up of in the story. To achieve the effect of the Mandrel braking down into the drug, a Mandrel costume was recreated using brittle foam and covered bits of it in latex, and had all of it attached to pulling wires and they then pulled it inwards and at the same time they were pumping smoke through it. When they finished the effect with a roll-back and mix, while putting in some more dust and the finished effect is probably the best effect in the story. When watching "Nightmare of Eden" it’s clear that the writer Bob Baker had thoroughly researched his ideas behind his script for "Nightmare of Eden", namely drugs and the scientific ideas behind the C.E.T machine (The Continuous Event Transmuter). The acting could have been better namely Lewis Fiander who played the character Tryst, he really could have done without the accent he chose to put on for the character and the square sun glasses. On the whole I still find Nightmare of Eden surprisingly enjoyable despite its flaws; it’s definitely not as bad as The Creature from the pit that's for sure.
