Who else but king Robert Downey Jr? IM and IM2 both grossed around $600m and that was pre-Avengers. Definitely gonna be much more successful this time around.
Monsters University
The Hobbit: The Desolation of Smaug
These are the only real two that stand a realistic chance at breaking the $1 billion barrier.
Iron Man 3 doesn't stand a chance in hell, so I don't know why its percentage is so high.
The Hobbit is the most logical choice since the first installment grossed a billion
But Iron Man isn't unlikely with The Avengers hype like y'all said, and Monsters U might come out of no where and slay like Toy Story 3 did
I'd like Oz to do it, but it's been released in every country already and hasn't passed $300m so I doubt it
Now gyal, I'm hopeful and all, but considering it took a collaboration of 4 different Marvel characters for them to break $1 billion, I just don't see it happening for Iron Man solo.
