Mario Bava does it again. The crystal colours, eerie atmosphere and evocative visuals are downright dazzling and haunting in this low-budget Italian Sci-fi outing. Never have I been disappointed in these technical aspects while experiencing the master at work. Many have mentioned it and the influences / similarities to Ridley Scott's 'Alien (1979)' ultimately sticks out. Even with that in mind it does share some ideas with the body snatcher theme, but it was a cleverly done concept done in a slow grinding, but extremely engaging style. The pacing is slow, but the flashy imagery and smoothly placed camera-work was hypnotic that it helped time flow by. My only real gripe was that the script was on the stilted side, but other than that it was one of those subtlety breezy mood pieces. More often the deaths happen off-screen and it's mostly free of action, to really only hit in the dying stages in some rapid set-pieces, but it's the dreary ending that's a strike of genius. Bava's crisp direction lets the otherworldly Gothic vibe take hold and while the sterile set designs look cheap it manages to be effective in its unusually stylish looks (add in seeping fog) and this invokes brooding unease and alienation. The surrounding sound effects and music score are creepily orchestrated. As for the special effects/make-up FX for such a low-cost production, they were well executed and ideally used. The acting can be rather rough in a staged sense with a dependable Barry Sullivan heading the way. Some of the characters were hard to tell apart though. A marvellously old-fashion, but influentially chilling space expedition.
