October 23, 2014 13 Nights of Hallowe'en 2014: Night #5 P2 (2007)
It just wouldn't be Hallowe'en without a psychotic predator. I don't know if a lot of people are familiar with this movie. I'll give you just a little description. P2 is about a woman trapped in her office building's parking structure on Christmas eve with a security guard who has been stalking her entirely unnoticed because he sees her for hours a day.
This is a great way to do a movie. Limited cast required, locked down locations, no consideration for time of day or night. It also requires that cast to be better than usual since they have so much screen time. I think they pulled it off. The movie plays more toward the thriller side than to horror, which I guess is why it doesn't get more play. It certainly has a nice gory kill among its thrills. I'll let you go get yourself locked in now.
