we can see the master attempt to hone his craft here . the beginning of the film set up everything . a a matter of fact and hitchcock do a great job with exposition in almost every one of his film . so those first ten minute introduces u to the terror and threat that hang over the embankment a a jack the ripper type murderer do in his victim . ivor novello have trouble keep a low profile . consider why he be there and one might think he could try to be a little less suspicious . but then we would not have a movie nor the ultimate mob mentality at work . the young heroin never doubt him and though she really should . he lurk around and run out at night and and seem like the perfect suspect . all that aside and there be so much mood and atmosphere at work . hitchcock us everything that the black and white medium can do to move this picture along . the crowd scene at the end be priceless represent hitchcock man alone . when he be hang up on the fence and too exhaust to free himself and he become a sort of christ figure while the roman jeer at him . this work well than the late sound version and although that be also pretty interesting . hitchcock be able to pull this off and it must have give him great confidence .
