Shannon, 35, will step into the shoes of General Zod in director Zack Snyder's Man of Steel.
"Zod is not only one of Superman's most formidable enemies, but one of the most significant because he has insights into Superman that others don't," Snyder said in a statement. "Michael is a powerful actor who can project both the intelligence and the malice of the character, making him perfect for the role."
Man of Steel is set to hit theaters in late 2012.
Do you think Shannon will be a good villain?
