Yeah, domestic appears to be certain but worldwide really depends on Japan and China.
Both are great Marvel markets, China especially is much better for Marvel than Star Wars, so there's a good chance there.
China's interesting because ethnic stories have been absolute gold the past few years like Coco as well as Bollywood movies.
So Black Panther really can do anywhere from $50 million to $200 million in China depending on word of mouth. That's the market to watch, if China's above $150 million then Black Panther worldwide has a solid chance at matching or exceeding $1.33 billion (TLJ's global take).
