"[Director] Schoedsack, endowed as he was with a great eye and a knack for special effects was – to put it mildly – one hell of a photographer and filmmaker. His work in this picture laid the visual groundwork (as Kong most certainly did) for generations of films and filmmakers to follow... "Dr. Cyclops" is not the masterpiece that "King Kong" was, but in its own special way, it was definitely ahead of its time in terms of both special effects and political/historical considerations and it amply provides solid entertainment to anyone who loves genre pictures. The picture's exploration of a "foreign" enemy wanting to experiment upon and ultimately subjugate American interests also pre-dates that attitudes so prevalent over one decade later during the sci-fi pictures made during the Cold War." - Greg Klymkiw, Daily Film Dose
