IM2 did 12.8m in japan and IM3 did 25.1m.
Thor did 5.7m in japan, so I'm gonne guess Thor 2 won't hit 10m.
That should put the final at $205m domestic, and about $435m overseas.
I'll say it first, I was off by quite a bit on the domestic side. I thought 225 was the absolute bare minimum it would make and it would very likely do over 250m, with 700ww an easy target.
To belabor the point very briefly, the avengers bump for IM3 was that it only dropped 20% of the avengers ww total, but the avengers bump for Thor 2 was that it made 40% more than Thor did.
