The good news is that it's still kicking butt in China,
with a $24.8m Saturday (+25.5% from its $19.75m opening day) for what should be a $63.5m Fri-Sun frame.
That's on par with Steven Spielberg's Ready Player One (which legged it to $218 million last year after a $61m debut in China) but it's also about on par with Kong: Skull Island (which earned $168m from a $71m launch in 2017) and Pirates of the Caribbean: Dead Men Tell No Tales (which earned $172m from a $65m launch in 2017). If it holds up at least as well as the 2017 releases, then it could hit $150m-$166m in China alone. That would be a great result but, pending how it performs everywhere else, not quite enough to make it a hit. Now if it plays like Ready Player One and flirts with $200m-plus (which is a big "if"), that's a different story.
Offhand, if it earns $175 million in China (How to Train Your Dragon 3 is "only" expected to earn $30m next weekend), $85m in North America and over/under $200m everywhere else (Maze Runner, Termiantor: Genisys and Ready Player One earned $220m-$238m overseas without China), then it still gets to a face-saving (if not money-making) $460m worldwide. However, if it goes the distance in China and holds up around the world, we could (again… "could") be looking at the first Hollywood flick to earn $500m worldwide without earning at least $100m in North America.
