i do not like to add much to the comment of my predecessor . this movie be interesting because it feature a very well make and elaborate cinematography which contribute much to overcome the script and act shortage . the color be well pick and the night exterior and interior scene be unusually subtle lit for this time . the camera always give room to the actor and dive into the action if necessary . the wheelchair camera in the hospital be something new for that time alongside the short lens action when the killer advance at the hospital stair . very contrasty and very colorful picture that do not look like the usual big lamp light that be usual for the 70ies in italy . the framing in the car motorcycle chase scene be also far above what be state of the art . long lens and big contrast variation and focus shift give it the edge . another hurray for the soundtrack represent stelvio cipriani vary only one theme ( schoolgirl variation and police or chase variation ) with great effect to it . this soundtrack be very typical for cipriani and almost as masterful a the one for mark il poliziotto .
