Nightmare Fuel / I Am Legend

  • Neville going into a darkened building, a likely place to find lots of Infected, to search for his dog. He's so obviously terrified you can't help but be frightened with him.
  • The zombies look very frightening.
  • One can't help but feel unnerved when Neville finds an immobile mannequin standing in the middle of the street, far from where it was supposed to have been resting.
  • The evacuation scene, and seeing the panic as hundreds of people are trying to flee New York.
