1. Warner Bros. really wanted the show to be called Slayer. Creator Joss Whedon refused.

2. Other actresses who auditioned for Buffy Summers included Katie Holmes, Selma Blair and Charisma Carpenter, who went on to play Cordelia…which was what Sarah Michelle Gellar auditioned for before being cast in the titular role.

3. In the unaired pilot, Willow (eventually inhabited by Alyson Hannigan) was played by Riff Regan. The 25-minute pilot presentation is basically the bane of Whedon's professional life, as he said it "sucks ass" in an interview with IGN.
