Alright lads, what's a movie that isn't considered horror by many (but you definitely think it is)?

Steven Spielberg's War of The Worlds adaptation without a doubt, and for those who disagree with me then consider these: The river of bodies, the crowd trying to break into Tom Cruise's car or ferry attack, the entire basement sequence, and how can we forget the martian terraformed countryside? I feel like the John Williams score is also worth a mention for its more ominous/sinister tone than his usual fare. Then again, I feel like you can make argument for WotW as being a horror story in general.
