This little film is among the best of Georges Sanders performances, where he is as exquisite as usual, as he was in Albert Lewin's features. This cynical and ruthless old dandy character suits him like a glove. The typical character that built his legend, an unforgettable actor. Landru, his character, is of course inspired by the notorious french serial killer from the forties. And, most of all, this movie is the best one made by W Lee Wilder who rather directed grade Z science fiction or thriller movies. This film, shown without the director's name, I would have never bet a cent on him. I even doubt that he actually made this film. It looks like an Edgard Ulmer's film instead, and certainly not W Lee Wilder, although some of his films were not totally dull either, crime flicks I mean, not Science fiction. Yes this is the W Lee Wilder's masterpiece.
