Warning: This article contains spoilers for the post-credits scene in X-Men: Days of Future Past.

We are getting our first peek–“peek” being the operative word here–at X-Men: Apocalypse.

Shortly after joining Instagram, X-Men helmsman Bryan Singer shared a photo of part of the movie treatment’s first page on Instagram and Twitter on June 30.

We get a peek at everything from the treatment’s start date (June 6) to co-writers (Simon Kinberg, Michael Dougherty and Dan Harris) to, of course, the tiniest bit of content.

The movie appears to open with a rehashing of the teaser scene at the end of X-Men: Days of Future Past, which featured a glimpse at the eons-old mutant Apocalypse and the Four Horsemen.

Naturally, fans were quick to react to Singer’s tease.

@ShawnRAshmore @BryanSinger This installment takes place the year I was born. I think it’s past time I make a cameo. Just sayin’. lol — Robert Scott Bean (@ILNY83) June 30, 2014

Since X-Men: Apocalypse is not slated for release until May 27, 2016, few details of the movie are known. Kinsberg told podcaster Jeff Goldsmith that it will take place in 1983 and, according to Entertainment Weekly, Michael Fassbender, James McAvoy, Jennifer Lawrence, and Nicholas Hoult will all reprise their roles as, respectively, Magneto, Charles Xavier, Mystique, and Beast.
