Why No Castillo?

Edward James Olmos turned down the offer to reprise his role as icy Vice leader Castillo for the Miami Vice movie. Word around the camp fire is that Olmos bailed because he felt Colin Farrell was too much of a bitch to bother working with. Personally, I feel that if Michael Mann can de-bitch-ify Tom Cruise, he can perform the same miracle on anyone. Olmos should have known this, and should have taken the chance to put a bow on the role that made all cop show bosses before and after obsolete. But then again, he was busy during the Vice movie shoot reprising a variation on the Stand and Deliver theme so close to his heart. And he was playing a dude named Julian ... who in their right mind would turn down that opportunity?
