Recently, Bryan Singer started an Instagram account - and his first picture was of a snippet of the opening to the X-Men: Apocalypse treatment. While only a bit of the text is readable, there are a few things you can glean from it: The Four Horsemen will play a prominent role and appear early on, the film opens with a battle of some sort happening in Egypt, and the writers of this movie need to include commas!
Still, much is left frustratingly vague. How does this all fit together with the post-X-Men: Days of Future Past continuity?
Luckily, we've managed to secure a leaked copy of the full treatment - and frankly, this looks like the most exciting and interesting X-Men film yet!
