To get back to the beginning, I think Little Chicago  was  useful for a couple of stories, and might have been great had Harry's story arc remained in Chicago.   But I think Jim thought it binding, that he was thinking beyond  Harry the Private Eye/Wizard, so it went up along with his, car, apartment and duster. And his 'old' life.

While it might have proven useful in past stories,  simply knowing it was there would have led people like us to ask "Why didn't Harry try Little Chicago When . . . .?"  I think it became a noose around his literary neck, as was the Beetle and some of the other tropes.   Harry's story began as a writing exercise,  built around classic PI fiction with a magical twist.  But as Jim wrote the world evolved and changed, and he began to see more interesting possibilities in it.   The Codex Alera shows his interest in the epic, and he began to see that Harry could be an Epic hero, with more humor and reluctance then most, but it's a line that might be carried through the story.   Little Chicago, the Beetle, his apartment, and duster were the sort of things that belonged to struggling PI Harry.  Epic Hero Harry doesn't really need those quirks, and in fact they hold him back a bit.   

This doesn't mean Harry stops eating at Burger King, or gives up his friends, but symbolizes that the stakes are rising, and the scale of his problems have left Chicago behind.

There are a couple of issues here.  One, if only an elect matter then societies will develop mechanisms to help these people learn and grow.  The successful will be better at it because knowledge is power.    Of course that means anyone opposing your favored God, will not want these elect to be successful.   They may become targets.    And how will this gathering of knowledge benefit/affect the living?  There must be some kind of feedback loop or the whole thing doesn't matter.

I am so amused that people seem to be giving this theory serious thought. 

Agreed.

Actually having recently seen The Imaginarium of Dr. Parnassus I think Lily Cole, who played  Parnassus daughter well capable of playing Lily.  Or any other person who needs to show both innocence and unearthly beauty.

Okay, I cast the movie and assuming I could get these people for an affordable price

Harry-  that's toughest really, because you need a really strong actor who's tall and rangy,  a younger Peter  Coyote mabye   but I'd choose Eric Bana or maybe Christian Bale

Murphy-  she'd be a little voluptuous but I really like Christina Ricci in that role, short, and does badassed very well with a bit of sweetness. 

Thomas-- Brad Pitt.  No contest here.
Morgan-- Alan Rickman    You need menace.  the problem is that before Turn Coat Morgan has few dimensions.
Lara Raith-- Nicole Kidman
Susan-- Rosario Dawson
Bob -- (voiced by John Goodman)
Butters-- Steve Buscemi or a young Wallace Shawn. Okay he's too old but what about Paul Reubens, who might be gettable.
Michael--  he's particularly tough because the actor must pull off Dudley Do-right without going over the top. He needs to  be underplayed.  Steve McQueen would have been perfect but he's too dead for the role.  okay, I'll go for Russell Crowe, who's versatile enough.  Or Gary Oldman.

Nicodemus -- Christoph Waltz--- have you seen inglorious basterds?   
Duke Ortega--  Benecio del Toro
Kincaid --  George Clooney
Queen Mab-- Lena Olin
Aurora-- Scarlett Johansson
Maeve-- Thora Birch (Christina Ricci being taken)
Madrigal Raith -- John Cusack
That's enough for now.

Question: Does SciFi own the rights to the Dresden Files?

I mean why should the show be stuck there?   Surely there are other venues, and frankly some shows have survived because of good DVD sales.

Why not look elsewhere?
