Note that extras tied to specific episodes are reviewed with those episodes.
Designing Buffy—This featurette is an overview of production design for the show. It includes interviews with Marti Noxon, Nicholas Brendon, Carey Meyer, Joss Whedon, David Greenwalt, Juliet Landau, Charisma Carpenter, Kristine Sutherland, and John Ritter. They discuss key sets such as Spike and Drusilla's factory, the library, the Master's lair, and the Bronze. Production Designer Carey Meyer narrated a tour of the set for Buffy's house and a shorter tour of Giles's apartment. It is of interest to people who want to learn about the technical aspects of filming the show, but it is optional for everyone else. It is very good at avoiding spoilers beyond the second season.
A Buffy Bestiary—This featurette covers many of the villains featured in the first two seasons including Darla, The Master, the Anointed One, Spike and Drusilla, the Inca Mummy Girl, Machida, Ethan Rayne, "Worm Guy," Patrice the Assassin, Ted, Lyle and Tector Gorch, the Bezoa, the Werewolf, Der Kinderstod, Amy the Witch, Fish Creatures, and the Judge, with most of the focus on Spike and Drusilla. It includes interviews with David Greenwalt, James Marsters, Julie Benz, Joss Whedon, John Vulich, Marti Noxon, Juliet Landau, Anthony Stewart Head, Kristine Sutherland, Danny Strong, Charisma Carpenter, Robin Sachs, Kelly Connell, John Ritter, Todd McIntosh, Elizabeth Anne Allen, Nicholas Brendon, and Brian Thompson (mostly Greenwalt, Noxon, and Whedon). The featurette is more about breadth than depth, but we do get a few insights. We learn the reason why the Master looks different from other vampires, that Spike and Drusilla were based on Sid [Vicious] and Nancy [Spungen], that Spike was supposed to be killed during the season, and that Danny Strong is ambivalent about not getting to kiss the Inca Mummy Girl. This featurette is probably more interesting to the causal fan than the one on set design. There are couple of spoilers for the third season.
Beauty and the Beasts—This featurette covers makeup on the show, focusing on both prosthetic monster makeup and beauty makeup. It includes interviews with David Greenwalt, Todd McIntosh, John Vulich, John Ritter, Joss Whedon, Kristine Sutherland, Nicholas Brendon, Charisma Carpenter, Julie Benz, Juliet Landau, James Marsters, Marti Noxon, and Brian Thompson (mostly with McIntosh, Vulich, and Greenwalt). Todd McIntosh and John Vulich described the steps necessary to create the vamp face prosthetic and also covered Ted, the sea monsters, and the Judge. Todd McIntosh also talked about how his knowledge of monster prosthetic makeup helped him with beauty makeup and how learning beauty makeup helped him produce prosthetic makeup. Besides being of interest to fans who are interested in how the show is produced, it also a bit more interesting to general fans than the "Designing Buffy" featurette is. It does not contain spoilers beyond the second season.
