At Comic-Con 2018, Joss Whedon debuted news of a new Dark Horse one-shot comic called Dr. Horrible: Best Friends Forever. Written by Whedon, the comic will feature art by José Maria Beroy (Versus) and Sara Soler (Red & Blue) with colors by Dan Jackson (Buffy the Vampire Slayer), cover art by Fábio Moon (Two Brothers) and a variant cover by Francesco Francavilla (The Black Beetle). Contrary to what you’d expect, the best buds referenced in the title are supposed bitter enemies Dr. Horrible and Captain Hammer.
IGN talked to Whedon about the new project, asking how these two could ever be described as “best friends.”
