Im sure one day a X-Men movie will hit 300m domestically. It could be Apocalypse... or not. But it will happen sooner or later.
One would guess after Dofp great reception, and with Apocalypse being a bigger, disaster type of movie and having fan favourites Cyclops, Jean, Storm, Nightcrawler and more.... it should have no problem doing much better than Dofp.
excited with the new casting additions for those roles
