I'm not a news breaking kind of guy, but I have knowledge of an actor who is playing a major (at least in the comics) Marvel villain who will debut in this series. I'd never heard of the actor before, so it's not a name anyone is going to guess, but he's done tons of work. I suppose he could have been lying or exaggerating his role in the production (since he's also a stuntman). But if he was being accurate this is a huge break for him.
For future reference in case he was being accurate, his initials are DR. Who knows...I'm excited to hear about the character though.
