Honestly wondering what trick the MCU is going to pull to make RDJ being both Dr. Doom and Iron Man make sense. Maybe he’ll just never have his mask off when RDJ is the actor, or maybe it will be multiverse shenanigans. I hope it won’t be like Coulson/Sarge in Agents of SHIELD wherein one is essentially a cosmic clone of the other.
I mean, RDJ did a decent job of playing a 60’s black charicature in Tropic Thunder. I think everyone is being quite ignorant to how an actors’ range works.
