I had the good fortune recently, to acquire an English language VHS copy of this rare 1951 movie; marketed then in the U.K. as; 'Mr. Peek-a-Boo'. My memory did not deceive me. It is still as entertaining today as it was when I first saw it in the cinema during the early 1950's. The originality of the movie holds well and seems to retain much of certain present day lost moralities. I give this very watchable film all the marks. The special effects are certainly not lost by todays cinematic standards. It's a great pity that movies like this seem to remain too long on the shelf. Actress Joan Greenwood and French comedy actor Bourvil, make you believe that a man can actually walk through walls. The superb supporting cast completes the illusion. Look out for it if you can.l
