As The Wrap reports, it's a stronger debut than The Dark Knight Rises' $32 million opening in China last year, and brings Pacific Rim's international total to a healthy $200.4 million. International success remains crucial for the film considering its weak box office performance in the United States; at only $93 million domestically after four weeks, it's still unclear if the film will break even considering its $200 million (approx) production budget and additional marketing spend.Pacific Rim will open in Spain, Japan and Brazil this week, its final three markets. Fans should keep their fingers crossed that its international performance is strong enough to justify a sequel.Lucy O'Brien is Entertainment Editor at IGN AU. Follow her ramblings onor
