"Infinity War prediction - 650 million domestically, 1.1 billion internationally"
Currently Infinity War is at 450 million domestically, 714 million internationally, and will get a boost from China soon.
I think my domestic could still be close, but internationally could exceed my prediction.
Both your opening weekend prediction in this thread ($250M) and your lifetime prediction are pretty good. I think domestic will be close to $650M but a bit higher than that. $670M perhaps.
