A discovery. Spectacularly well shot and deftly acted (Neergaard and Price are different types and they work really well opposite each other). The strongest part of the film is the premise constructed through the first part of the film. After that, it loses its momentum because Ravn stops elaborating, satisfied to deal with the complications relating to the double, some of which are hardly believable. Nevertheless a must-see for anybody with even a fleeting interest in sci-fi.
