The scene in school at the beginning, from about 6:43 to 10 minutes on DVD, is all filmed in a single take. From the library, through the cafeteria to the hallway, with six main actors, about a hundred extras and nearly fifty lines of dialogue.
This is the first use of the remastered Buffy theme. It will be heard in the opening credits through the remainder of the series.
First time the "real" goth Buffy logo in the main title.
