I thought Ortega was supposed to be a conquistador.  I think Bratt looks closer to that than Quezada.

How about Danny Trejo as the Red King?

Wayull...the Arabs (Banu Umayya through the Almohadins) ruled Spain for about 800 years.  Which almost certainly means their contribution to Spaniard genotype (and hence phenotype) was probably disproportionate to their numbers.  This was certainly the case with Sicily before the Crusaders conquered Palermo, and the heritage is apparent in many Sicilians to this day.  A Conquistador with darker phenotype is by no means improbable.

Ebenezar McCoy (the Blackstaff):



And he does a variety of accents, including hillbilly.  Occasional lapses into Scottish shouldn't be a problem.

Warden Carlos Ramirez (bearded and beardless versions):

He just slotted into place. Michael B. Jordan is the one thing I’m looking forward to about the new F4 movie.

I’m still utterly stuck for Butters and Bianca though.

I picked Michael Shannon either for Agent Tilly or Fr. Roarke Douglas.  Wish I could agree with your commendation of forum participants for not complaining about your choice for Billy Borden, but when I suggested Will Smith for Harry the villagers gathered with their torches and pitchforks.  Despite the fact JB himself made the same call.

PS: Pat Morita woulda been my pick for Shiro, if he was still living (may Allah have Mercy on him).

Lord Hern/the Erl Koenig (will require some makeup/prosthesis, but he's been there, done that):

Lupita Nyong'o as the Angel of Death in GS (always envisioned her for the part):

Vadderung/Odin/Kringle:







(First choice was Kris Kristofferson, but recent photos of him suggest he'd be too old for Vadderung, unless makeup and maybe CGI could fix him up sufficiently).
