Kneeling confirmed...

General Zod will be the antagonist of Zak Snyder's new Superman -- the Man of Steel and he'll be played by Michael Shannon. Shannon was nominated for Best Supporting Actor in Revolutionary Road and was seen most recently in HBO's Boardwalk Empire. It will take one heck of persona to fill Terence Stamp's jackboots, but Shannon is intense and seems capable of being Kal El's most formidable nemesis, the former commander of Krypton's armed forces.

So no Viggo Mortensen. In fact this (almost) makes the second role Viggo's been mentioned for that he's lost, as it sounds like Javier Bardem is 99% locked as Roland for The Dark Tower films, with a formal announcement due any day.

Me, I'm just happy to hear that they are going with Zod, as I think that sets up an action-packed clash of wills, which is exactly what Superman needs. Here's hoping Michael Shannon makes a worthy opponent.
