Nightmare Fuel / Maleficent: Mistress of Evil

• The red iron dust. It's made from the flowers that mark the graves of fairies and a single touch of it can kill anything it touches. The scene introducing it feels like a deliberate homage to Who Framed Roger Rabbit's The Dip.
  • It's not just killing them, it's burning out their essence and leaving behind what plants they resemble. A walking tree turns into a real one while others become just plain flowers.
• When it hits the Dark Fey, it just turns them into clouds of ash in mid-flight.
• The scene in the church would not be out of place in a Holocaust movie. Hundreds of fairies are lured into a chapel, waiting to see their queen marry, and then are trapped inside as iron dust is released into the air, killing everything it touches. Some fairies shield others with their bodies to protect them from the dust.
• Queen Ingrith's redheaded servant (whose name is Gerda). Period. She has seemingly no motivation for doing Ingrith's bidding outside of sadism and Fantastic Racism, and yet she gleefully plays the rigged organ to kill all the fairies, working up to it by playing a melody first and then afterwards hitting the rigged key at random to space out bursts of dust and thus prolong the suffering.
• Queen Ingrith herself isn't any better, even if she's more subdued about it. Her Evil Plan basically involves a genocide of a living, sentient race, which she proceeds to do so with gleeful abandon and get rid of anyone who's getting in her way, even her own husband, son, or Aurora - her soon to be daughter-in-law. It says something about her state of mind when the secret entrance to her underground workshop could only be opened by twisting a mannequin's neck violently.
