I saw this at a private screening at the cinema during my student days (not at Harbour Lights, but at that other independent venue near the Mayflower theatre though the name escapes me). At the time the film was banned (I'd previously seen a fairly good quality pirate video of the film). The letter of the law meant the film could be shown, but only for educational purposes to students on the appropriate courses. Loads of horror fans who weren't on our course tried to blag their way into the screening, but were refused admission. They booted several people from inside the screening too, checking course IDs twice!
