Kinda glad it's not Khan, myself. If they were to cast Khan, you'd think that today they'd actually cast someone with Indian bloodlines and not lilywhite Benedict Cumberbatch. Sunil Shetty would be a pretty badass Khan. Though I could see Ben Kingsley too....he'd make a great "Khan as a dictator" type.
Alice Eve as Carol Marcus? I like that too. Hope she's more than a damsel in distress.
