Great casting, if you ask me. Amy Adams is funny, full of spirit, and dare I say, kinda hot. And she's going to be Lois Lane in Zack Snyder's SUPERMAN: MAN OF STEEL, according to Hero Complex.
It wasn't clear for a while that Lois would even be in this new iteration, but thankfully the character remains because she's a challenge both to Clark Kent and Superman. Now that she's been cast, it's difficult to think of anyone else playing the part. That's perfect casting, in my opinion.
I know Snyder's said Viggo Mortensen isn't going to be Zod, but now that Mortensen won't be in SNOW WHITE AND THE HUNTSMAN, perhaps a reconsideration would be in order? Or should he use another character altogether?
