Variety report that Richard Schiff, the Emmy Award winning West Wing actor, will join the cast of Warner Bros. and Zack Snyder's Man Of Steel as a character "dubbed" Dr. Hamilton.
Yes, dubbed, but before you jump to any Lex Luthor type conclusions, "Professor Emil Hamilton" is a comic book character. He has appeared in numerous Superman stories, most recently in a villainous capacity as he begins to see Supes as a potential threat to the world. It is unknown where his loyalties will lie in Man Of Steel. A younger incarnation of the character also appeared in Smallville. Schiff has appeared in numerous movies and tv shows including Se7en, Jurassic Park 2, ER and The Sarah Connor Chronicles.
