Pretty sweet. If a studio was to obtain license to make a movie, they should have it set sometime during the founding of Fabletown. Central conflict would be Fables refusing to adapt to the secret life, or the founding of the Farm even.
I'd never considered this casting, but it's really really good. The guy i always had in mind is Thorsten Kaye- not only does he look the part, but he's got a really gruff, gravelly voice that would go well- you should google him sometime.
