La cabina

I have not seen this film for a while but I have seen it several times on TV and I have never forgotten it. It is a film with minimal dialogue and pieces of classical music. The story is simple. A man takes his son to school. On the way home he enters a telephone box which has its door slightly ajar, like a venus fly trap waiting to snare its victims. He finds it is out of order and cannot open the door. He is helpless. People try but fail to get him out. Then the phone company's truck arrives along with several men. I won't reveal anymore but the finale is terrifying and shocking and is unforgettable. I first watched this movie when I was eight-years-old and after I wouldn't go into a phone box for a while in fear of being trapped inside. One of the truly great films.
