I think Klaw is a potentially great role a number of actors could sink their teeth into. Viggo Mortensen would be great. Sharlto Copley would be great. I've seen Vincent Cassel's name thrown around quite a bit, and he'd be great. Some other good suggestions I've seen are Bryan Cranston, Ed Harris, and William Fitchner. Waltz could do it, but it would probably feel like retreading old territory for him.
It should be someone, I think, who can convey sort of an old school colonial imperialist vibe. I'd be interested in seeing what Colin Firth could do, playing against type.
