According to Variety, Richard Schiff, formerly of The West Wing, has been cast as Doctor Hamilton in Zack Snyder's upcoming re-imagining of the Superman mythos, Man of Steel. Although the article doesn't elaborate on the role much, there is little doubt that "Doctor Hamilton" is Emil Hamilton, a character from the comics that has been both an ally and adversary of Superman.
With Michael Shannon already confirmed to be playing the villainous General Zod, it doesn't seem likely that Schiff will be portraying the maniacal version of Hamilton just yet; however, with Man of Steel serving as the first part of a potential Superman trilogy, it is possible that his turn towards evil could certainly begin in this first movie.
Schiff will be joining a star-studded cast that already includes Henry Cavill, Amy Adams, Diane Lane, Kevin Costner, Michael Shannon, and Laurence Fishburne.
Man of Steel will hit theaters on June 14, 2013.
