Now that Henry Cavill is locked in to play the Man of Steel, Zack Snyder is getting to work filling his Superman film's non-Superman parts with Kevin Costners and the like. Next on Snyder's list: filling the part of villain General Zod--last portrayed theatrically by Terrence Stamp and v-neck pajamas--and the Hollywood Reporter seems to think Viggo Mortensen is first in line to be knelt before in the role, which could be a fun chance for the actor to fight someone while wearing clothes this time, even if those clothes end up being v-neck pajamas.
It should be noted, though, that--as with Costner--talks have not yet started, and as of now, Mortensen is only being fitted with the criminal-sounding label of "person of interest." He could be pretty good in the part, though, yeah? Plus, with this and the Lord of the Rings trilogy under his belt, he'd be guaranteed prime seating in the "celebrity" section of comic conventions until the day he dies. $40 photo ops is always a good option for a fallback career, Viggo.
