Zack Snyder's upcoming Man of Steel sequel (which annoyingly still doesn't have an official title) is gearing up for production, and this week three new actors jumped on board the already controversial superhero movie: Holly Hunter (The Incredibles, Saving Grace), Callan Mulvey (300: Rise of An Empire, Captain America The Winter Soldier), and Tao Okamoto (The Wolverine). According to Deadline, they will be playing new characters, but take that news with a grain of salt. Joseph Gordon Levitt and Miranda Tate played "new" characters in The Dark Knight Rises, and look how that turned out. Mulvey in particular could fill the shoes of some other costumed hero, so you can bet we'll be watching this news closely.
