these film of the 1930s and 1939 in this case and be amaze . simple acting and yet still quite inspire by silent movie technique . very simple set not clutter with too many useless prop and other decoration . the dialogue be necessarily simple and the voice work be a caricature of dramatic speech . it be all record directly when the film be shoot on a sound stage most of the time and the microphone be still very primitive . so what could you expect . no integrated music and no sound effect or very poor one and no visual effect of course with most of the time sedentary camera . and the lighting be still far from particularly brilliant . and yet these film be magic because they do not even try to look real and realistic . they have to work the way the technique dictate it . then the rest be compensate and supplement by the imagination of the audience . and the zipper in the back of the monster be not bother anyone at the time since it be such a marvelous improvement to have the puppet on the screen speak in real voice . it be amazing to see such an old film by hitchcock . he be already a great director who could get some real gripping action or situation even with all the shortcoming of his equipment . we have to watch them again these old film and these first talkie and to and be able to appreciate what modern film have to offer but also what we have lose along the way and a lot more than we may think and and particularly the magic of black and white illusion . but we can not be and have be at once and that obvious . so let u be live in our time and nostalgically revisit the past . dr jacques coulardeau and university paris dauphine and university paris 1 pantheon sorbonne .
