Re: Holly Hunter, Callan Mulvey & Tao Okamoto Join Superman/Batman Movie
Hunter is probably a politician or diplomat. Someone heading up the civilian govt (UN?) response to the arrival of aliens and super-powered beings.
The 300 guy is obviously muscle of some type. Good or bad I have no idea. Probably a bad guy.
The girl from Wolverine could be a Luthor bodyguard. I've no doubt she will probably be the opponent for WW.
