Here's a pretty ancient interview from jan, 2000. Maybe it's been posted before. Just had lots of compelling comic-booky goodness....
"The way I saw it, a Buffy series was my chance to make high school horror movies on a weekly basis. I got all excited about doing it, and here we are. I never expected it to spin off into another series and end up consuming my life in the way it has."
In crafting the Buffy television series, Whedon assembled a cast of characters that from the outset seemed like an odd collection of individuals. When examined more closely, however, it becomes clear that Whedon had subconsciously built a super-hero team.
--------------
Lets look.
--------------
We've got Rupert Giles, the mentor; Buffy Summers, a vampire hunter; Daniel "Oz" Osborne, a werewolf; Willow Rosenberg, a witch; Spike, a Wolverine-esque vampire, Anya Emerson, a former demon; and Xander Harris, a wise-cracking sidekick who fills the "Snapper Carr" role.
While Whedon said his interest in comics had waned somewhat in the late '80s and early '90s, it wasn't until after the Buffy television series was on its way to becoming a hit that he realized he'd crated a traditional super-hero team. "I didn't really think about comic-book-ness of Buffy and Angel until recently, when I had a huge renaissance of devouring all the comic books I can find," Whedon said. "Then, I looked back at Buffy and said 'Oh, yeah, well, duh. This was always a comic book.' But early on, I didn't really quite understand how the sensibility of comic books had influenced me. Now, I think it's pretty obvious, when you look at what I've done."
"Someone recently referred to the Buffy-Angel shows as the 'Blade-Hannibal King Block.' I have no comment at this time," Whedon said, laughing.
Whedon's realization that he'd created a comic-book-inspired team of heroes was bolstered by Buffy series writer Doug Petrie, himself a longtime comics fan. "Doug came up in the comics world around the same time I did, and we started going over all the old stuff," Whedon said. "It was Doug who was able to point out that a storyline in Angel was very much like when The Silver Surfer went back to Zenn La and other, shall we say, strikingly similar storylines that were apparently in my subconscious. The two of us spend a lot of time together talking comics--some would say it's an inordinate amount of time--some might even say we waste a lot of time talking about comics. But they give us a wide berth as they pass us by, so we keep talking..."
"...Back to comparing his series to comics, Whedon said he feels that Angel is much more than just a Batman riff, as some critics are labeling it and Angel's assistant Cordelia (Charisma Carpenter) hints at it on the show. "I see Angel more in terms of film noir then I ever do of a comics sense," Whedon said. "But, if I had to choose a comic book that fits his ability, it would be somewhere between Batman and Tomb of Dracula with a little E. C. horror thrown in. If I had to choose a super-hero, Batman would probably get the nod. But I didn't go out and say, 'Let's make a Batman.' I wanted to make a good, dark, noir-esque series about a vampire looking for redemption..."
"...With his firmly established love of genre material, Whedon said he has mixed feelings about adapting a comic book to a feature film.
"Every time I see a bad comic-book movie--and, so far, I've yet to see a good comic-book movie--it breaks my heart," Whedon said. "Part of me would really love to do a comic-book movie--Hell, I'd love to do a Spider-Man or Batman. Those things mean a great deal to me and have the potential to be wickedly cool."
"On the other hand, with Alien and even Buffy, I'm getting tired of working in things where 14,000 people own the rights. On Buffy, there are a lot of people who are attached, but I basically can make my own stuff, and that fine. With something like a Marvel comic book, you know you're going to be into heavy interference. I've dealt with that before and I'm not really that anxious to do it again. It would have to be a pretty special deal to make it worth the bother."
