To make sure that you have a happy Halloween we've compiled a small list of eight films that will keep you awake at night. Lars von Trier's Antichrist proved that chaos does reign. In The Shining the Overlook Hotel is scary enough, but add in ghost twins and it's just scarier. The film Funny Games may be more terrifying than horrifying but scary all the same. 1980's The Changeling is another haunted house story but this time with balls. Hitchcock's Psycho will make you rethink showers ... and corpses. It may have come from a scary game, so it had a head start in the fright department, but Silent Hill will definitely keep you up at night. Session 9 proved that abandoned mental hospitals weren't scary enough. Pulse, or Kairo as it's known in its native Japan, is quite horrific but, also a fantastic film.
