I've always pictured Eric Roberts as Marcone...Nicolas Cage's Balthazar in "The Sorcerer's Apprentice" was very Dresden - also most of Cage's characters are full of wise cracks in tense situations. I'd probably go with him.

Of the lot in the suggested list - I think Paul Bettany could really pull it off, make-up would need to do something about his fair colouring though.
