You might have missed Ryuhei Kitamura's Midnight Meat Train when it was in theaters a few months back. It's horror flick from a story by Clive Barker, starring Vinnie Jones, about a dude who kills people on the train. At midnight.
Lionsgate kind of gave it a crappy limited release, so barely anyone really saw it. Also, it has a really awful title. To be honest, I don't know if it's any good. But guess what? You can watch it online now over FEARnet. For free! Something scary for your Halloween.
