"Menace de mort" is directed by Raymond Leboursier, an occasional director (only 8 movies) and writer, with no masterpieces in his filmography. This one is a kind of film noir. The major problem is the love story, quite far fetched and played by Colette Darfeuil and Jean Martinelli, completely dull and wooden, in fact, I do not see one scene where they're in love. Maybe it was the director's intention to be so wrongly dark, because the rest of the casting is as we can expect : a boozy Pierre Renoir, the smart concierge Pierre Larquey, and the real interest of this movie, the fallen inspector Dalio who plays delightfully a kinda of nasty Columbo tracking Jean Martinelli. He's really exceptional. Oh, and just enjoy the very last shot, so "unique".
