I saw this film last night. Unusually, it is filmed entirely in black and white. It's also unusual in that the first film is watched as a film by the main character and used as a reference by him. It's also unusual in that an actress from the first film plays herself in this film.
This isn't a film I can recommend to anyone. I didn't enjoy it very much but watched it nonetheless. The main characters dialogue is none existent. He has a job as an underground car park attendant. He has a tire iron as a favourite weapon which he swings with abandon but doesn't kill his victims with it. The film doesn't make sense to me but maybe I'm thinking too much about the biological aspects. I wouldn't recommend this film to anyone apart from fans of the first film.
