an upbeat and happy delivery of the line "most of it", as opposed to a sad, depressed delivery. Hannigan figured Willow would be happy and proud that she got "most of it" back. That indicated how she was going to play the rest of the scene, and the role, for that matter, and defined the character. Her approach subsequently got her the role. Opening sequence The Buffy opening sequence provides credits at the beginning of each episode, with the accompanying music performed by Californian rock band Nerf Herder. In the DVD commentary for the first Buffy episode, Whedon said his decision to go with Nerf Herder's theme was influenced by Hannigan, who had urged him to listen to the band's music.

Halfyard describes sequences, in which the action and turbulence of adolescence are depicted, as the visual content of the opening credits, and which provide a postmodern twist on the horror genre.
