Batman Begins/Nightmare Fuel


 * Batman Begins asks the question: "Would you like to see Dr. Crane's mask?" It doesn't help that he's using a chemical that could literally be called Nightmare Fuel.
 * Batman's whole shtick is to be Nightmare Fuel to his enemies.
 * The end sequence where the Narrows are just teeming with Fear Toxin, and all the escaped convicts see Batman flying above. Their collective hallucination paints Batman as a huge black shadow with GLOWING RED EYES! It then distorts his voice to an even more horrible growl... Though it is quite the subversion in that it's the HERO that's terrifying.
 * Also, Crane's vision of Batman while on the toxin.
 * "Dr. Crane isn't here right now. But if you'd like to make an appointment..."
 * And Batman's vision of Crane when he got sprayed with the toxin.
 * BUF Special Effects (the team who created the Scarecrow effects for the film) released an FX reel after the film came out that highlighted several sequences from the film. One of them is a deleted shot featuring Rachel's perspective of Crane when the elevator doors open in Arkham. In the theatrical cut, Crane immediately grabs her when the doors open. In the FX reel, Crane stands there staring straight into the screen with a passive look while maggots fall off of his face.
 * How about that poor guy that used drugs that Crane tampered with in The Dark Knight, who rolls around pleading "Get them off!" while clawing at himself?
 * Some of the songs on the soundtrack are downright creepy, like "Artibeus" and the middle of "Macrotus." Whispering can be heard in some of them. The sound of bats can be heard in one of these songs too. It makes sense, but it's still really freaky.
 * When the Narrows  Oh so many things are freaky in this scene. The riots, the images of Batman , Zsasz walking towards   with a knife, the crowds of people attacking  , the monorail once built to help Gotham being used   and more.
