When Buffy the Vampire Slayerended its run in 2003, it didn't just fade away. Sunnydale might have been obliterated, but the Joss Whedon universe was buzzing with the possibility of other spinoffs, television films, and big screen appearances. Over the last five years, that has become increasingly less likely, especially in the wake of the popular comic continuation. So I am sharing the following only in the interest of keeping up on rumors, not because I believe it.
According to Moviehole, the Herald-Sun Newspaper had a small blurb on Buffy, which said: "Rumours are circulating in Hollywood that Whedon has a feature-film script based on his hit TV series ready to roll as soon as a studio is prepared to commit." While it's entirely likely that he does have some Buffy scripts floating around, I'd be wonderfully surprised to hear that one is all ready. Besides his busyness with the new television show, there's the comics, and more specifically -- a storyline that has continued beyond the show.
Would Joss somehow pull Angel and LA out of hell and have Buffy round up the Scooby gang? The only scenario I can imagine would be Buffy bringing Angel and LA out of hell. It would be epic enough for the big screen, and be an endeavor that would bring back all of the cast (except Anya... boo hiss!). But that's just a dream, and while this rumor sounds swell and I could go for many more years of live-action Buffy, I ain't buyin' it. Are you?
