I tried adding up the opening weekend from everywhere together, and if Avengers had opened everywhere all at once it would have made at least 412m ww, and possibly as high as 440m.
So, what's the chance that Avengers 2 will make over $500m WW in its opening weekend?
I think low to mid 500s. My general impression is that spiderman has reached market saturation and there will be little growth from here on out aside from inflation. I could be wrong though. We'll see.
I think Catching Fire will just barely get to the far side of $500m overseas. I'll say $515. The reviews are very positive (surprisingly so IMO, but then again I'm not a huge fan of the first one and haven't read the books), however I think that will be a bigger factor for the domestic box office.
I was all into predicting superhero movies this past summer, and I put down $275-$350 million overseas for The Winter Soldier (and $200-260 for North America). But for the sake of giving a single hard number I'll go with $325 million.
I see both domestic and overseas numbers for Furious 6 moving up just marginally from Fast 5, around $250 and $500 respectively. That's still pretty incredible, top 75 all time domestic and top 50 all time worldwide.
And I think pushing out number 7 next year is too soon. That one will probably see either a plateau or a slight drop in both numbers.
