43% also thought Avengers Age of Ultron would get over $2 billion in global box office.
Avengers 2 will not reach that level. Avengers 2 is at about $1.37 billion (once last weeks foreign box office is counted. Avengers still has to open in Japan.
It will be lucky to get to $1.6 billion globally and get past the first Avengers box office (without inflation adjustment for the first movie).
