some people say the pace of this film be a little slow and but how be this different from any other hitchcock movie . they all move very deliberately and and a a point and have spurt of suspense and brilliant montage inject through it . this movie give u just the right amount of comic relief which make the suspense scene seem all the more suspenseful . the albert hall scene be one of the best example of pure cinema that exist in hitchcock collection ( the best probably be almost all of rear window ) . pure cinema for hitchcock mean a series of usually small piece of film fit together without dialogue and in order to tell the story visually . this be and of course the basic definition of the albert hall sequence and as well a the shorter staircase sequence at the end of the picture . not many slip ups by hitchcock here and and the acting be superb especially by doris day in a rather surprising serious role .
