Would I watch the movie?
I would watch the ENTIRE series of movies, actually. Especially if they were done by DF3. That cast is SO cool. Their Michael Carpenter even did an epic NSFW/NSFSanity ALS challenge thinger:
I HAVE NO REGRETS THIS IS GOD’S WILL.
Seriously, though, I think this really will work better as a TV series instead of a movie. There’s just too much that needs to be covered in order for this to work as a movie franchise.
And yes, I know that we already HAD a Dresden TV series starring Laurel Lance’s “worst cop ever” dad on “Arrow”. But that show somehow didn’t feel as Dresden Files-y as it could have been. If it had been a more faithful adaptation, well…

If I were to believe the Jim Butcher site, the next book’s tentative title is “Peace Talks”. I wait with bated breath.
And I’ll probably re-read the series over and over again.
This, and all the previous Dresden Files books, are available at all bookstores, including online stores like Book Depository and Amazon.
