Ah, but the plot thickens! It turns out that Whedon was offered the chance to helm the reboot of his beloved franchise, but he turned it down. At least so says the trusty Hollywood Reporter.
Now, Whedon fans (and there are plenty of you out there), before you go off bemoaning what could have been, sit down for a moment, think quietly and ponder this one simple question: "Do I really want Joss Whedon to go back to the 'Buffy' well? Do I really want to see him squander his talents remaking a character and a universe he already perfected a decade ago?"
For Whedon to limp back to 'Buffy' when he's got Marvel's 'The Avengers' on his plate -- well, that's just silly.
There are two additional ways to look at Whedon's decision to stay clear of this project. The first one is easy enough: it's a case of Whedon realizing that there are bigger fish to fry and it's time to move on, spread his wings and try something new. What's past is prologue and the future holds many a splendored thing and so on and so forth. Although Whedon has made it clear that he's not happy with the character in someone else's hands, he realizes that he doesn't need the character.
Then there's Whedon's complicated relationship with 'Buffy' rightsholders Fran Rubel Kuzui and Kaz Kuzui, whom Whedon blames for the failure of the original 1992 'Buffy the Vampire Slayer' film. As director, Fran Rubel Kuzui transformed Whedon's acclaimed script into a goofy mess that Whedon has since disowned, but due to their initial involvement, the Kuzui's recieved major producer credits on each and every episode of the Whedon-orchestrated 'Buffy' TV series even though they had absolutely no involvement with the development of the show. It's unclear how involved the Kuzui team will be in the 'Buffy' reboot, but it's hard to imagine Whedon having any desire to work with them again.
Of course, that was two paragraphs of educated guesswork and speculation. Knowing the talkative and open Whedon, we'll see all of the details spill from his own mouth soon enough.
