surprisingly I could live with that.Yeah, I wouldn't rule out Ronan the Accuser. His name keeps popping up again and again in the GOTG rumormill, with a new actor "attached" to the rumor each time. Vin is the only one I've heard so far who makes sense as Ronan, as a bad mf you wouldn't want to run into in a back alley in some rundown spaceport somewhere.
Maybe Vin is playing a villain? Korvac? I Always thought Michael C Hall would make a great Korvac (visually speaking anyways) but Vin is a pretty good actor.
If he's not a villain perhaps Adam Warlock
I didn't think they'd get someone of Vin Diesel's caliber (fame wise, not talent wise) to voice Groot. I thought that was just a role that would go to a crew member. But if it is Groot that's be awesome.
To be perfectly honest, I think it'll turn out to be a case of people --- even actors --- not knowing (or caring) that "Marvel" isn't one big happy family: it's several separate film universes scattered out over at least three studios. My money on this meeting with Vin is that it's actually Fox, and he's who they've got tapped for Ben Grimm.
