an amazing piece of film that be well conceive and keep me on the edge of my seat . brilliantly orchestrate in it timing and and the comedy kick in exactly when the tension need a release . the acting be generally well do ( the director should have ask alec guinness for act lesson ) and and the shot selection be impressive ( a in elongate the hall a billy try to race to the door in the studio ) . this movie do not let up since the opening scene .
