X-Men: Apocalypse opens to $8.2 million at Thursday previews 20th Century Fox‘s X-Men: Apocalypse earned $8.2 million at Thursday previews domestically, which is similar to the $8.1 million X-Men: Days of Future Past grossed its first evening. We’ll have to wait and see where the Bryan Singer-directed film will end up for the four-day Memorial Day holiday weekend, though Fox thinks it could be $85 million or more. X-Men: Days of Future Past opened to $110.6 million for the four-day Memorial Day weekend in 2014. X-Men: Apocalypse had already earned more than $130 million overseas before it opened in North American theaters yesterday.
