Heck, I'm just going to write a pitch...
Director: Robert Rodriguez (El Mariachi, Desperado, Once Upon A Time In Mexico, Sin City)
Storyline: A hard nosed Inquisitive, a retired paladin, a young psychic warrior, and a sociopathic Warmage cross paths several times in Sharn over the course of a few days, as each pursues his own personal goals, eventually bringing them together for good or ill...
Writer: Frank Miller (Sin City, 300, hell... you know what he's done), Neil Gaiman (Stardust, Sandman, various comics and novels), and Keith Baker (Duh). Miller would give us the grit we need for an urban noir tale, Gaiman would inject the wonder we want for the setting, and Baker would make sure it was all true to Eberron's theme.
Cast: Honestly, I'd need to write up a full treatment to get an idea of the cast. And if I was going to do that I think I'd be PMing it to you. Of course... If you'd like me to do so...

Format: Live Action
Producer: Rodriguez, 'cause he seems to know what's cool. And we can trust him not to get in the director's way, because he's directing.
Effects house: I haven't been impressed by ILM lately, nor WETA. Both seem a bit flashy to me. I'd be more likely to go with the companies behind Sin City, League of Extraordinary Gentlemen, Pan's Labyrinth, etc. For the most part we want subtle, not over the top.
I don't really know enough about studios and the economics of moviemaking to really say much for the studio and budget.
