20. James Marsters, who played Spike, wasn’t actually British. He’s from California and auditioned with a Texas accent, but producers decided it would be better if the character was a Londoner. Head served as his dialect coach throughout the series.
21. Gellar sometimes struggled with the dialogue, which was branded Buffyspeak and inspired by California Valley girls.
22. In fact, there is a book out explaining the slang in the show – Slayer Slang: A Buffy the Vampire Slayer Lexicon.
23. Whedon knew he wanted either Willow or Xander to come out as gay, but it took him a while to eventually choose Willow.
24. Darla, played by Julie Benz, was supposed to die in the second episode. But Whedon kept her alive to make the Buffy/Angel romance a bit more interesting.
25. The show was shot in a warehouse and actual schools because they had such a tight budget in the early days.
26. But producers later built their own graveyard in the warehouse’s parking lot to make their life easier for shooting scenes.
27. The cast hated filming all of the scenes in the library because it would always mean a lengthy speech for Head.
