With a 3-day holiday weekend in its corner, X-Men: Apocalypse will only earn $65 million domestically [$78 million across 4-days]. That's a disappointing figure when compared to Batman v Superman's $166 million and Captain America: Civil War's $179.1 million. This figure is also way down from Days of Future Past's $110.6 million opening weekend gross.
But all is not lost. The last two X-flicks attributed the bulk of its worldwide box office total to foreign territories. X-Men: First Class amassed a "41% domestic/59% international" split on its $353.6 million worldwide total. It's follow up, and Bryan Singer's return to the franchise, Days of Future Past had an even larger divide with a "31% domestic/69% international" division of its $747.8 million worldwide haul.
If Apocalypse is headed for another "30% domestic/ 70% international" split of its revenue and analysts are predicting a $170 million finish for its domestic run, the worldwide box office haul for Apocalypse would come in at roughly $567 million. Of course, this estimate applies a similar precipitous drop for the film's international totals. It's entirely plausible that the film's international box office could account for 80-90% of its worldwide gross.
UPDATE: International numbers for Apocalypse are a little more hopeful. The film has earned $55.3 million in its second weekend of international release, bringing its global total to $250.8 million.
