But while X-Men: Days of Future Past combines the classic X-Men cast (e.g., Patrick Stewart, Ian McKellen) and the newer X-Men stars (e.g., James McAvoy, Michael Fassbender, Jennifer Lawrence) into one star-studded extravaganza, X-Men: Apocalypse will just follow the First Class team. Although First Class is one of the franchise’s lowest grossers, the studio is banking on Days of Future Past to give the younger stars the momentum they need to make X-Men: Apocalypse a hit.

X-Men: Age of Apocalypse will mark the sixth X-Men movie overall (or eighth, if you count the two Wolverine flicks), the fourth X-Men movie that Singer has directed, following X-Men, X2, and X-Men: Days of Future Past, and his first focusing solely on the First Class cast. As for when exactly production will get going, or what precisely the plot will entail, that remains to be seen.

In the meantime, X-Men: Days of Future Past opens May 23, 2014. Since Singer clearly isn’t going anywhere, let’s just hope it’s good.
