Motion Picture Purgatory: Inception
We can hear the grumbling already. Yes, we know Inception isn't a horror movie, but it's a terrific mindfuck and certainly has some dark and twisty elements. Besides, Trembles took the time to draw up a Motion Picture Purgatory for it, and we've never been the type to look a gift horse in the mouth.
The film is directed by Christopher Nolan (certainly no stranger to the "thriller" category of genre films) and stars Leonardo DiCaprio, Joseph Gordon-Levitt, Ellen Page, Tom Hardy, Ken Watanabe, and Cillian Murphy.
In a world where technology exists to enter the human mind through dream invasion, a highly skilled thief is given a final chance at redemption, which involves executing his toughest job to date: Inception.
