Here's the exact moment when Robert Downey Jr. announced his #Marvel return for AVENGERS: DOOMSDAY:

I hate this idea. There seriously wasn't another actor available to play Doom?

And why is that a good idea???? It erases his past as Iron Man.... "You either die a hero or you live long enough to become the villain"

Excited but scared Disney will mess it up. 😱😱😱

I was expecting a different actor. I feel that I will think of iron man when I see rdj. Hope he’s not the definitive dr doom. Just a multiverse variant.

this is insane

Why?? There are plenty of actors who aren't Iron man.

The only people that agree with the idea is the nerds in the room.

😂 😂 😂 What a dumb idea.

Somewhere Steve Rogers is turning in his grave lol

Doesn’t sit right with me, especially after his legendary run as iron man. Horrible idea.
