Trivia / Buffy the Vampire Slayer S1E10 "Nightmares"

  • Actor-Shared Background: Alyson Hannigan maintains that she cannot sing or dance (which hasn't stopped multiple writers from shoehorning her into splashy musical numbers, but oh well), and requested her part in Once More With Feeling be limited.
  • Completely Different Title:
    • French: Billy
    • Portuguese: "Pesadelos" (Nightmares)
    • Finnish: "Painajaisia" (Nightmares)
    • German: "Die Macht der Träume" (The Power of Dreams)
  • Deleted Scene:
    • A line of Xander's was cut from the original script due to length:
    Okay, despite the rat-like chill that just crawled up my spine, I'm going to say this very calmly: Helllppp ...
    • An exchange between Giles and Buffy was also cut from the original script due to length:
    Giles: Are you all right? You look a bit piqued.
    Buffy: Hospital lighting. It does nothing for my fabulous complexion.
    Giles: Are you... sleeping all right?
    Buffy: I'll sleep better when we find this guy. Nothing like kicking the crap out of a bad guy to perk up my day.
  • Enforced Method Acting: Sarah Michelle Gellar has a fear of being buried alive, proving once more that Joss Whedon hates humanity.
