On Monday, director Bryan Singer launched a new Instagram account with a shot of the first page of the treatment for X-Men: Apocalypse, the sequel to X-Men: Days of Future Past.

It references the Nile, and “the Four Horsemen,” the henchmen of the powerful mutant Apocalypse — clearly evoking the post-credits sequence for Singer’s film X-Men: Days of Future Past, which became the top-grossing film in the franchise globally.
